Foreword
Fuel Cells are electrochemical devices, which convert chemical energy
of gaseous fuels, hydrogen in particular, directly to electrical energy with
significantly high conversion efficiency. The principle of fuel cell was
demonstrated more than 175 years back. However, its technological
importance has been recognized for the last half a century or so. Concern for
climate change in recent years has accelerated the development of this
technology world over so that the carbon cycle of energy production can be
changed to hydrogen cycle within the shortest possible time. Almost all the
developed and developing countries have earmarked billions of dollars for
development of this technology. Consequently, a significant progress has
already taken place. A large number of prototypes are being operated by
different countries. All the auto-giants are aggressively developing fuel cell
driven automobiles in an attempt to cut down greenhouse gas emission.
India being a highly populous country is also concerned about its
contribution to climate change and therefore has been giving significant
importance to generation of renewable energy e.g. solar and wind. Hydrogen
energy has also been a focus of attention for quite some time. Unfortunately,
required emphasis could not be given primarily due to resource crunch and
therefore the progress is lagging far behind in the global race. Under this
premises, the Ministry of New and Renewable Energy, Government of India
constituted a high power Steering Committee to prepare a status report and
way forward for hydrogen energy and fuel cell technology in this country. One
of the five sub-committees was entrusted with the responsibility of preparing
this particular document concerning the development of fuel cell technology.
I am indebted to all the members of the Sub-Committee, other experts
(Dr. Venkat Mohan, Indian Institute of Technology, Hyderabad, Dr. Irudayam
Arul Raj Central Electro-Chemical Research Institute, Karaikudi, Dr.
Venkatesan V. Krishnan, Non-Ferrous Technology Development Centre,
Hyderabad) for their contribution, Dr. M. R. Nouni, Scientist ‘G’, Ministry of
New and Renewable Energy and also the officials of the Project Management
Unit – Hydrogen Energy and Fuel Cells at the Ministry, Dr. Jugal Kishor and
Dr. S. K. Sharma in particular for their active and invaluable contribution
preparing this document.
This report is expected to be of immense use to all the stakeholders
related to the activities in the area of Hydrogen Energy and Fuel Cells in the
country.

The first meeting of the Sub-Committee on Fuel Cell Development in
India was organized on 29.11.2012, in which presentations were made by the
expert members of the Sub-Committee in their areas of specialization and
discussions were held subsequently. The expert members provided input
materials for preparing the draft report. The input materials were presented in
the second meeting held on 02.09.2013. Based on the input material, the
report on Fuel Cell Development in India was drafted and presented in the 2nd
meeting of the Steering Committee on Hydrogen Energy and Fuel Cells held
on 11.06.2014. The Steering Committee recommended constituting an Expert
Group to prepare a list of focus areas within the areas identified for National
Mission Projects, for which R&D proposals may be invited and supported by
the Ministry for the time being. This Group met on 02.09.2014 and identified
the focus areas within the areas identified for National Mission Projects, for
which R&D proposals were invited to support by the Ministry. The finality of
the report was discussed in the 3rd meeting of the Steering Committee on
Hydrogen Energy and Fuel Cells held on 26.03.2015. The Steering
Committee gave some suggestions, which were discussed in the meeting of

EXECUTIVE SUMMARY

1.0 Executive Summary
1.1 The need for developing appropriate technologies for harnessing
renewable and/ or alternate sources of energy have gained significant
importance globally, including in India, in view of increasing use of fossil fuels
both for power generation and transportation with consequent environmental
concerns on one hand and depleting reserves on the other. In this context,
fuel cell technology, which can address these issues, is attracting a
considerable attention.
1.2 A fuel cell is an electro-chemical device that converts chemical energy
of a fuel into electricity and produces heat & water. The fuel cells using
different electrolytes operate at different temperatures. Fuel Cell developed so
far are Low and High Temperature Proton Exchange Membrane Fuel Cell
(LT- & HT-PEMFC), Direct Methanol & Ethanol Fuel Cell (DMFC & DEFC),
Phosphoric Acid Fuel Cell (PAFC), Alkaline Fuel Cell (AFC), Molten
Carbonate Fuel Cell (MCFC), and Solid Oxide Fuel Cell (SOFC). A few more
fuel cells e.g. Bio-fuel cell (BFC), MEMS based micro fuel cell (MFC) and
Direct Carbon Fuel Cell (DCFC) are at different stages of development. The
operating conditions, fuel capability, performance characteristics including
conversion efficiency and application potentiality of these fuel cells are quite
different.
1.3 Polymer electrolyte membrane fuel cell (PEMFC) has the potential to
be deployed in portable, small capacity power generation and transportation
applications. These fuel cells have high power density and can be operated at
low and high temperatures at variable loads. The LT-PEMFC can be easily
started-up and stopped at low temperatures -35 to 400C and thus currently a
leading technology for deployment in the light and heavy duty vehicles. To
resolve the issues of LT-PEMFC such as requirement of pure hydrogen due
to low tolerance of Pt (a costly noble metal) catalyst to CO and humidification
of membrane for migration of protons from anode to cathode, HT-PEMFC,
which operates in the temperature range of 120-1800C are being developed.
1.3.1 PEMFC technology has been developed to the commercialization
stage in many countries like Canada, USA, Japan, Germany etc. As per
Industry Review, the shipment of PEMFC units dominated in 2011 for the
stationary and transport applications. In India a large number of groups are
engaged in the research, development and demonstration activities of
PEMFC but it has not reached the stage of commercialization. A few
organizations like CFCT-ARCI, CSIR-Network Labs, NMRL, VSSC, BHEL are
engaged in complete development of PEMFC system. Engineering input and
infrastructure for producing such system in large numbers for trials /
demonstration are lacking. These activities rely on pressurized bottled
4
hydrogen procured at high cost. On site hydrogen generation units (reformers)
operating on commercial fuels such as LPG, methanol or natural gas are not
available in the country, which again restrict the technology development
process.
1.3.2 Development of HT-PEMFC continues but with limited number of
commercial deployments so far.In Denmark a 3 kW system has been
demonstrated. Another 5 kW unit hasbeendeveloped for telecom application.
Danpowerfrom Denmark has recently announced that they can supply the
high temperature membrane in larger sizes and quantities. Prefabricated
MEAs are also available from limited suppliers. Important attraction of this fuel
cell is the tolerance of up to 3% CO in the fuel (hydrogen) and the possibility
of using combined cycle system for heat recovery. Further developments in
HT-PEMFC are awaited.
1.3.3 Globally, it is expected that Power supply system of 25 lakh telecom
towers will be converted to fuel cell based power system by 2020 and
potential of global market for stationary fuel cells will reach 50 GW by 2020.
All the major automotive manufacturers have a fuel cell vehicle either in
developmental or in testing stage. Some of them will start large scale fleet
operation from 2015. In India, development of fuel cells is not reached to the
stage, at which they may be taken up for manufacturing. Therefore, a strategy
is required at national level to address the issues like balance of system
development, system integration, manufacturing R&D for fabrication of repeat
components and their demonstration. Other issues like power density at a
given cost, weight, and life time, which have commercial importance, are also
to be taken up for further R&D.
1.4 The phosphoric acid fuel cell (PAFC) operates in the temperature
range of 190 to 2200C and hence is capable to use reformed hydrocarbon
fuels or biogas with less than 2% CO. These fuel cells have been used widely
for different stationary power generation applications in the range of 100 - 400
kW. The electrical efficiency of PAFC is about 40% and combined heat and
power efficiency is around 85%. These systems were used in military
applications in USA. M/s Toshiba and M/s Fuji electric Japan developed this
technology for power generation with online reformer based initially on
propane/LPG and later on CNG / landfill gases with a life time of more than
45000 hours. In India, PAFC a system of 50 kW capacities was developed by
the Bharat Heavy Electrical Ltd. (BHEL) sometime back. Unfortunately, the
work could not be taken up further, because of non-availability of carbon
paper at that time. BHEL also imported, installed and operated a 200kW
PAFC unit from M/s Toshiba Corporation of Japan with LPG as the primary
fuel. Later, Naval Materials Research Laboratory (NMRL), Ambernath also
developed such systems of 1-15 kW capacity and demonstrated successfully
5
for field applications. The technology has been transferred to M/s Thermax
Ltd, Pune and around 24 numbers of 3kw units have been manufactured for
DRDO’s captive use. This is the only example of a successful indigenous
production of fuel units in India even though on a buy-back
arrangement.Presently NMRL is engaged in development of underwater
power solutions together with improved versions of field powering for remote
and sensitive areas.
1.5 Alkaline Fuel Cell (AFC) in which an aqueous solution of KOH is used
as the electrolyte, is a low cost technology because of its components are
made from inexpensive materials. It can be operated in the temperature range
-400C to 1200C. It is a reliable source of electricity generation leading to
higher energy efficiency i.e. up to 60%. AFC was initially used to provide
electric power and drinking water in Apollo spacecrafts.However, AFC
operating with air on the cathode suffers from CO2 contamination and reduces
output and also enhances the cost. In addition the problem of an appropriate
electrode material is still to be solved.Presently there is a large effort to
develop anion exchange polymeric membrane, which can replace the
aqueous potassium hydroxide hitherto used. It can be deployed in various
other applications such as telecommunication towers, scooters, auto-
rickshaws, cars, boats, household inverters, etc. So far there has not been
any technology development effort in this country even though limited basic
research has been carried out by a few academicians.
1.6 Direct Methanol Fuel Cell (DMFC), which uses methanol, a product of
renewable sources, as fuel. It is in liquid state at normal temperature and can
easily be stored and transported. This fuel cell is best suited to applications
requiring power less than 100 W like computerized notebooks, mobile
phones, military equipment and such other electronic devices. SPIC Science
Foundation, Chennai was the first in the country to demonstrate a 250 watt
stack in early 2000. Later CSIR–CECRI designed, developed and evaluated
for continuous operation of a 50 watt stack. R&D is being continued for
further improvements. The researchers have shifted their focus to use ethanol
in place of methanol due to methanol being lower in molecule size (tendency
to crossover more than ethanol), having low boiling point (more loss), being
toxic in nature and has comparatively low energy density. IIT, Delhi
developed a 3 W stack using Nafionmembrane and a novel bi/tri metallic
catalyst with a performance of 50-70 mW/cm2.
1.7 The Solid Oxide Fuel Cell (SOFC) uses solid, nonporous metal oxide
electrolytes like yttria stabilized zirconia (YSZ) together with oxide based
electrodes. There are two forms depending on the operating temperature.
High temperature ones operates in the rage 800 – 10000C while the
intermediate temperature ones operate in the range 550-8000C. For high
6
temperature variety internal reforming is possible. Fuels like gasoline, alcohol,
natural gas, biogas etc. can be reformed internally on the anode surface
producing hydrogen. This hydrogen generates electricity in the fuel cell.
External reforming is required for intermediate operating temperatures.
SOFCs have been developed in two different designs i.e. tubular and planar
types. Both have their merits and de-merits in their fabrication and operation.
Initial development by Westinghouse or Siemens-Westinghouse was centered
on high temperature tubular type and up to 200kW units have been
demonstrated with natural gas as the fuel. Most of the recent developments
are in the area of intermediate temperature one. Several institutes and
commercial houses across the countries like USA, Canada, Germany, UK,
Denmark, Australia, and Japan have demonstrated the operation of a large
number of units up to 25kW capacity with planar configuration. High power
density relatively low temperatures of operation are the two most attractive
features of the planar design. Commercialization of SOFC technology
particularly for stationary power generation seems to be viable as many
prototype demonstration units are operating for a considerable length of time.
In India, R&D activity on materials development for SOFC technology followed
by stack development and testing have been in progress for more than two
decades and has just reached a stage of technology demonstration on a
relatively large scale. CSIR-CGCRI, Kolkata has recently demonstrated a
500W anode supported stack with planar configuration using ferritic steel as
the bipolar plate. Efforts are on for further scale-up in association with an
industrial collaborator. Another major effort in development of the 3rd
generation technology (metal supported SOFC) has been underway since
2012, by NFTDC, Hyderabad in collaboration with University of Cambridge,
UK, for development up to the level of a SOFC stack. This project is funded
by DST-RCUK (as part of the Indo-UK, UKIERI program).Several other
institutions of the country have also developed the R&D capability on different
aspects of the technology. Monolithically integrated micro-SOFC can replace
Li-batteries for certain type of applications.
1.8 Molten Carbonate Fuel Cell (MCFC) uses an alkali metal carbonate as
the electrolyte in the molten phase. Most common electrolyte is the eutectic
mixture of Li2CO3 and K2CO3 in the ratio of 62 to 38 mole% and operates at a
temperature of about 6500C. The higher operating temperature provides the
opportunity for achieving higher overall system efficiencies and greater
flexibility to the choice of fuels. Unlike other fuel cells MCFC anode can
oxidize carbon monoxide in the fuel to carbon dioxide through electrochemical
reaction. However, the limitation associated with MCFC is the management of
carbon dioxide produced as product of combustion. The high operating
temperature imposes limitations and constraints in selection of suitable
materials of construction for long time operations. MCFCs can be used with
both external and internal reformers. Recently, field tests of a 2 MW internal
7
reforming system at the city of Santa Clara, California and 250 kW external
reforming by San Diego Gas and Electric, California have been demonstrated
and a 280 kW system hasstarted up in Germany. A 1 MW system has also
been installed at Kawagoe, Japan. Extensive developments are still required
before commercial applications become a reality. In India not much
development activity has been undertaken so far on MCFC except an attempt
by CSIR-CECRI, Karaikudifor the development in laboratory scale of multi-cell
stack. TERI, New Delhi also carried out a small demonstration project based
on an imported MCFC unit with financial support from MNRE.
1.9 Bio-fuel Cell (BFC): The fuel cells, which convert biochemical energy to
electrical energy through an electrochemical reaction by usingdifferent forms
of bio-catalysts, are normally referred to as “Bio-fuel Cells”. There are two
major types of Biological fuel cells (or Bio-fuel cells): 1) Microbial fuel cells
employ living cells such as microorganisms as the catalyst for the
electrochemical reaction and 2) Enzymetic bio-fuel cells, which use different
enzymes to catalyze the redox reaction of the fuels. The range of substrates
for BFCs is unlimited and depends on the biocatalysts being used to drive the
reactions to generate power. The production / consumption cycle of bio-fuels
is considered to be carbon neutral and, in principle, more sustainable than
that of conventional fuel cells. Moreover, biocatalysts could offer significant
cost advantages over traditional precious-metal catalysts through economies
of scale. The most important advantage is wastewater treatment with
production of energy. However, the magnitude of power reported so far in
BFC is several orders less than the conventional chemical fuel cells. The
potential areas for its power application are portable electronics, biomedical
instruments, environmental studies, military and space research etc. In India,
many institutions are active in this area. Their primary focus is to develop
suitable electrodes materials or tweak the microorganism. Mediator-less and
membrane-less MFCs have been demonstrated in laboratory scale. In India
many small groups are active in the area of microbial fuel cells (several
reviews have been published by Indian groups in the last ten years) but the
primary focus is to develop suitable electrodes materials or tweak the
microorganism. Mediator-less and membrane-less MFCs have been
demonstrated by a couple of groups and proof-of-concept demos have been
carried out at IICT, IIT-Khargpur, CECRIand NTU although this is an area
where India could do substantially better given our strengths in chemical,
biochemical and microbial engineering together with interdisciplinary
capability.
1.10 Direct Carbon Fuel Cell (DCFC) converts fuel (granulated carbon
powder ranging from 10 to 1000 nm sizes) to electricity directly with a
maximum electrical efficiency up to 70% (with 100% theoretical efficiency).
The systems, which may operate on low grade abundant fuels derived from
8
coal, municipal and refinery waste products or bio-mass are under
development. The byproduct is nearly pure CO2, which can be stored and
used for commercial purpose leading to zero emission. The program is
developing the next generation of high temperature fuel cells.The cell design,
materials development program and fabrication technologies have specifically
focused on developing a device that can be easily up-scaled. This has led to
the use of conventional ceramic processing routes but novel cell designs and
materials to fabricate cells that can be easily stacked, connected electrically
and operated continuously on solid fuels for extended periods of time with
minimal degradation. Several laboratories in USA and Australia are active in
the development of such a device that can easily be scaled up. No work in
this area is reported so far from India.
1.11 Micro fuel cells (MFCs) are the miniature form of either PEMFC or
DMFC or SOFC and have the potential to replace batteries as they offer high
power densities, considerably longer operational & stand-by times, shorter
recharging time, simple balance of plant, and a passive operation. Micro fuel
cells are ideal for use in portable electronic devices (fuel cell on a chip). As
per CSIRO, Australia if these are mass produced; they can be delivered at
low cost and cover large volume markets. Such micro-fuel cells and
disposable methanol cartridges have been developed for mobile devices.
Polymer electrolyte micro fuel cells can be used in 3D printing, which is
effectively carried out on a large area. There is an ever increasing demand for
more powerful, compact and longer power modules for portable electronic
devices for leisure, communication and computing. Low cost lithographic
techniques have been developed for fluid flow micro channels. Other features
include self-air-breathing or stack-powered air supply, 100% fuel utilization, no
air or hydrogen humidification, ambient temperature operation, low catalyst
loading, life time over 20,000 hrs. The other type based on monolithically
integrated SOFC on a Si ship is also very important as planar configurations
can be effected using modern manufacturing processes to make Li-batteries
obsolete for certain type of applications. Unfortunately, there is no tangible
activity in India and therefore there may be an opportunity to initiate
preliminary work.
1.12 Governments in many countries are providing support at various levels
like research & development, demonstration and deployment of fuel cell
systems not only to research laboratories but also to industries.Severalbillion
dollars have been spent by various Governments in promoting fuel cell
research and development at different levels over several decades.
Investment by industries has also been quite substantial. In contrast, Indian
funding has been significantly low; MNRE, DRDO, CSRI, DST, BRNS, DSIR
being the major contributors. A fewIndian Industries are also quite keen in fuel
cell technology development and demonstration. During the last 10 years
9
MNRE spent around Rs.25 Crore on fuel cell research. CSIR also spent
around a similar amount during this period. In addition DST and DSIR
contributed around Rs.5 Crore each for the similar purpose. DRDO has so far
invested around Rs.50 Crore and plans invest another Rs. 100 Crore in near
future. Exact amount spent by DAE is not available at this stage but likely to
be of the order of Rs.50 Crore during the last 10 years.
1.13 In order to revisit the “Hydrogen Energy Road Map” prepared in 2007,
the Ministry of New and Renewable Energy constituted a Steering Committee
on Hydrogen Energy and Fuel Cells in 2012 under the Chairmanship of Dr. K
Kasturirangan, the then Member (Science) Planning Commission,
Government of India to advise the Ministry and steer overall activities and its
five Sub-Committees on various aspects of hydrogen energy and fuel cells for
in-depth analysis. The Sub-Committee on Fuel Cell Development is one of
them, which met thrice under the Chairmanship of Dr. H.S. Maiti, Former
Director, Central Glass and Ceramic Institute, Kolkata and currently INAE
Distinguished Professor, Govt. College of Engineering and Ceramic
Technology, Kolkata to thrash out various issues pertaining to the indigenous
development of complete fuel cell systems and their commercialization in the
country.
1.14 Major Recommendations:
1.14.1 Basic Strategy
Identification of Mission Mode projects, which may be implemented by
pulling together resources from different governmental agencies.
Prioritization of technology development and field level demonstration
activities in comparison to normal laboratory development.
Focus should be provided for manufacturing both at the assembly line
level and also indigenization of the critical components.
Identification of critical applications where Fuel cells can play a
dominant role and develop the appropriate Fuel Cell technology for
these applications.
Promotion of critical mass of projects and identification of areas
requiring funding both to set-up manufacturing facility as well as initial
deployment through Viability Gap Funding (VGF) and R&D funding
mechanisms.
10
Identification of the USP like Combined Heat & Power (CHP) integrated
with the Fuel Cells which provide an enhancement in efficiency, a
quantum more than the current state-of-the-art.
Keeping the strategic sector apart, one may create two consortia for
telecom and CHP and the consortia should include institutions, industry
and project developers. The first consortium may be on low to medium
temperature PAFC / PEM while the second consortium could be
around SOFC.
Provide significant emphasis on quantifiable targets and deliverables
together with enhanced professionalism in project monitoring and
management.
1.14.2 Classification of Projects
a) After a careful analysis, the Sub-Committee suggests that all the
institutions involved/ interested to work in this area may be brought
together to put their efforts in a coherent and cohesive manner and by
pooling together all the resources available with them to achieve a
common goal i.e. development of specific fuel cell systems in the shortest
possible span of time. It recommends that the Government of India may
support the projects in three categories viz. (i) Mission Mode Projects (ii)
Research & Developmental Projects and (iii) Research Projects
(knowledge base generation).
Based on the application potentiality as well as available expertise in the
country, the types of fuel cells identified for Indigenous development of the
technology in Mission Mode(Category I) are:
i) HT-PEMFC with combined cycle (Joint Lead Institutes: CSIR-NCL,
Pune and CSIR-CECRI, Karaikudi)
ii) LT- PEMFC (Lead Institutes: CFCT, Chennai and/or CSIR-CECRI,
Karaikudi/ BHEL R&D, Hyderabad)
iii) Planar SOFC (Lead Institute: CSIR-CGCRI, Kolkata)
iv) PAFC /for civilian applications only (Lead Institute NMRL, DRDO,
Ambernath and/or BHEL R&D, Hyderabad)
All national mission projects must have industry collaboration.
The areas for conducting Research and Development (Category II)
activities have also been identified, which are:
a) DMFC/ DEFC
b) MCFC
c) BFC
Industry collaboration is preferred but not essential for this category of
projects.
11
Basic/ Fundamental Research Projects (Category III) may be
sponsored preferably to the academic institutions/ universities and IITs for
all other varieties of fuel cells including AFC and Direct carbon fuel cell
(DCFC).
No lead institution is identified for the last two categories of projects.
Projects may be approved based on the merit of the proposals.
b) Under the Mission Mode Projects, development of stand-alone systems of
following capacities may be taken up in a phase-wise manner:
• 1-5 kW for back-up power supply unit for urban households,
• 3-5 kW for telecom towers,
• 3-10 kW for small trucks,
• 10-15 kW for medium trucks,
• 25 -50 kW for large trucks and submarine application and
• 50-120 kW for buses
In the first phase, the projects may be targeted for development and
demonstration of minimum 5 units each type of systems of capacities 1, 3
& 5 kW with a minimum of 50% indigenized components.
Particularly for the PEMFC units, targeted electrical efficiency would
be 37-40%; minimum 1000 h operational life and less than 10 mV / 1000 h
degradation; to be operated with bottled hydrogen and air may be taken up
initially. During the development, manufacturing techniques should also be
mastered.
Recognizing the fact that the all ceramic fuel cell namely SOFC will
be primarily used in stationary applications as distributed power sources,
the targeted capacities should be in the higher range. In this case the
suggested specifications may as follows:
Capacities :5, 15 and 25kW
Minimum power density :1.5W/cm2
Operating temperature :8000C (max)
Fuels to be used :Impure hydrogen/Natural gas/Biogas
Fuel Utilization :70% (min)
Minimum life span :40,000hrs
Imported components :50% (max)
c) All Mission Mode projects are to be inter-institutional with industry
participation. One of the institutes may be identified as a nodal Institute
and would be made responsible for the ultimate delivery of the project
objectives. MNRE may take proactive measures to identify the projects
and seek “Expression of Interest (EOI)” from the identified lead institutes in
12
association with Indian industries. Foreign collaboration, if required may
also be accepted.
d) Financial Outlay: An overall budget provision of around Rs.750
Croresmay be made available for a period of next 7 years (till 2022)
for technology development and research on all categories of the activity
mentioned above; 80% of which may be earmarked for mission mode
projects (category I), 10% for Research and Development projects
(category II) and 10% for knowledge base generation (category III). As a
part of the mission mode activity, it would be essential to establish a
“Centralized Fuel Cell Testing Facility” for independent evaluation of all the
fuel cell units proposed to be developed under the programme.
e) Pure hydrogen is required for the operation of LT-PEMFC. Since
transportation of bottled hydrogen makes hydrogen costly, on-site
hydrogen generation is preferred but the imported reformers are very
expensive. It is therefore suggested that hydrogen generation projects
should also be supported simultaneously with the fuel cell development
projects. Chlor-alkali Industries and other industries where hydrogen is
available as by-product should be encouraged to install large fuel cells
stacks (50 kW or more) in their premises. Incentives could be provided for
public-private partnership for such installations.
f) In addition, development of appropriate technologies for generation,
storage and transportation of the fuels, in particular pure hydrogen have to
be give due emphasis to match with the requirements of the above
mentioned fuel cells. According to a rough estimate overall requirement of
1,500 million liters hydrogen may be required for the proposed
developmental programme. It is expected that the same will be taken care
of by other sub-committees specifically constituted for this purpose.
1.15 Policies, Procedures and Legislation:
For each Mission Mode project a consortium may be formed consisting
of R&D groups, academia and industry (both manufacturer and user)
and representatives from the funding agencies.
While the lead Institutes may be decided by the ministry (as
recommended above), identification of the other participants may be
done through news paper advertisement of “Expression of Interest”
followed by selection by an “Expert Group” to be constituted by the
Ministry.
Projects need to be formulated with sufficient micro-detailing in terms
of technical specification, target and time frame.
13
Rigorous monitoring and risk management together with mid-course
correction, if required, should be an integral part of project
management in order to keep the projects on track.
Important but uncertain activities may be duplicated if required.
For projects other than mission mode, industry participation may not be
essential. However, micro detailing and rigorous monitoring have to be
ensured.
Provision of fore-closing a project should be practiced as and when
necessary.
1.15.1 Virtual Fuel Cell Institute (VFCI):
In order to ensure implementation of all these policies and procedures,
a strong and fully-empowered R&D management group is essential at the
level of the ministry. It is therefore proposed to establish a “Virtual Fuel Cell
Institute (VFCI)” to coordinate all the activities related to country’s Fuel Cell
Development Programme” It will help bringing together all the concerned
stakeholders such as Ministries, Departments, academicians, researchers
and industry under one umbrella to work together and pool their resources.
The Institute may function through a strong “Advisory Committee” with
representatives from different stake holders.
1.15.2: Modality of establishing the VFCI and its modus-operandi may be
decided by MNRE in consultation with other departments/ agencies if
required.

2.0 Introduction
2.1 All over the world, including India, the need for the development of an
alternate energy sector, which is becoming increasingly important not only
due to our need to reduce dependence of rapidly exhausting fossil fuels, but
also due to increasing global concern about the environmental consequences
of the uses of fossil fuels in generation of electricity and for the propulsion of
vehicles. There are more than 1 billion automobiles in use worldwide,
satisfying many needs for mobility in daily life. The automotive industry is
therefore one of the largest economic forces globally employing huge people
force and generating a value chain in excess of $3 trillion per year. As a
consequence of this colossal industry, the large number of automobiles in use
has caused and continues to cause a series of major issues in our society as
follows:
2.2 Greenhouse gas (GHG) emissions—the transportation sector
contributes ~13.1% of GHG emissions worldwide (5 billion tonnes of CO2 per
year). More than two thirds of transport-related GHG emissions originate from
road transport. Reducing the GHG emissions of automobiles has thus
become a national and international priority. Air pollution—tailpipe emissions
are responsible for several debilitating respiratory conditions, in particular the
particulate emissions from diesel vehicles. The increasing number of diesel
vehicles on roads would further worsen air quality. Oil depletion—oil reserves
are projected to only last 40–50 years with current technology and usage.
Transport is already responsible for large share of the oil use and this share
continues to increase. Energy security—India dependence on foreign sources
for its oil and reserves of conventional oil are concentrated largely in politically
unstable regions; dependency on fossil fuels for transportation therefore
needs to be reduced in the country. According to the United Nations, world
population reached 7 Billion on October 31, 2011and is expected to reach 8
billion in the spring of 2024 & 9 billion by 2050. This will obviously have an
important impact on climate change, food security and energy security. The
development of alternative fuels to petrol and diesel has therefore been an
ongoing effort since the 1970s, initially in response to the oil shocks and
concerns over urban air pollution. Efforts have gained momentum more
recently as the volatility of oil prices and stability of supplies, not to mention
the consequences of global climate change, have risen up political agendas
the world over. Hydrogen has emerged as environment friendly alternate fuel.
A number of devices / systems have been developed / are under development
for power generation / transportation applications with hydrogen as fuel. Fuel
cells are low-carbon technologies and have already been recognized to
address all the above issues related to GHG emissions, air pollution, energy
security etc. and are thus rapidly advancing in global technology and industrial
domain Today, fuel cells are widely considered to be efficient and nonpolluting
18
power sources offering much higher energy densities and energy efficiencies
than any other current energy storage devices. Further, the fuel cells like
other small-scale generation systems such as wind turbine, photovoltaic,
micro-turbines, etc. play an important role to meet the consumers demand
using the concepts of distributed generation. The term distribution generation
means any small-scale generation is located near to the customers rather
than central or remote locations. Survey showed that at the end of year 2005
the total loss over the transmission, distribution and transformers in India was
about 32.15 %. The major benefits of distributed generation systems (DGS)
are saving in losses over the long transmission and distribution lines,
installation cost, local voltage regulation, and ability to add a small unit instead
of a larger one during peak load conditions. Among the different distributed
generation systems greatest attention is being paid to the fuel cell because it
has the capability of providing both heat and power. Fuel cells are therefore
considered as promising energy devices for the transport, mobile and
stationary sectors.
2.3 The fuel cell has its own importance, as it is an energy conversion
device that converts chemical energy of a gaseous / liquid /solid fuel into
electrical energy by electrochemical reaction. In this device electrolyte (non-
conductive to electrons and conductive to charged species) is sandwiched by
the two electrodes (cathode and anode). Hydrogen, when fed to anode, splits
into proton and electron in presence of catalyst. The electrons flow through
conductor and charged species pass through electrolyte membrane to
cathode, where they combine with oxygen to produce heat and water as
byproducts. The water, so produced, does not have any pollution footprint. It
is environmentally benign. Fuel cells operating with hydrogen as the fuel do
not produce any gaseous pollutants like CO2, CO, NOx, SOx etc., which are
normally released by conventional power plants.Efforts are being pursued
over the globe to enhance the efficiency of fuel cells and coupling with
devices to utilize the waste heat for energy conservation. Therefore, owing to
the advantages associated with fuel cell technology, security of electricity can
be ensured in future, which is also expected to induce a new era of ‘hydrogen
economy’.
2.4 Fuel Cells are a family of most efficient energy conversion devices in
which the chemical energy stored in a fuel is converted to electricity by a
single step electrochemical reaction. This is in contrast to a thermal power
plant in which conversion takes place through a multistep process.
2.5 Fuel cells differ from conventional electrochemical cells and batteries.
Both technologies involve the conversion of potential chemical energy into
electricity. But while a conventional cell or battery employs reactions among
metals and electrolytes whose chemical nature changes over time, the fuel
19
cell actually consumes its fuel, leaving nothing but an empty reservoir or
cartridge.A common example of conventional electrochemical technology is
the lead-acid automotive battery. Another is the lithium-ion battery. Some
conventional cells and batteries can be recharged by connection to an
external source of current. Others must be discarded when they are spent. A
fuel cell, in contrast, is replenished merely be refilling its reservoir, or by
removing the spent fuel cartridge and replacing it with a fresh one. While the
recharging process for a conventional cell or battery can take hours, replacing
a fuel cartridge takes only seconds.
2.6 Hydrogen may be obtained by reforming various gaseous fuels like
producer gas, biogas from organic waste or other biomass, natural gas,
liquefied petroleum gas and liquid fuels like methanol, ethanol etc.
2.7 Various kinds of fuel cells have been developed over the past few
decades. They are classified primarily by the kind of electrolyte they employ.
This classification determines the kind of electro-chemical reactions that take
place in the cell, the kind of catalysts required, the temperature range in which
the cell operates, the fuel required, and other factors. Important types of fuel
cell under development are: Low and high temperature Proton Exchange
Membrane Fuel Cells (LT- & HT-PEMFC), Direct Methanol Fuel Cells
(DMFC), Phosphoric Acid Fuel Cells (PAFC), Alkaline Fuel Cells (AFC),
Molten Carbonate Fuel Cells (MCFC), Solid Oxide Fuel Cells (SOFC). In
addition, there are a few types of more recent origin, which have also gained
significant importance in recent years. These are MEMS based micro-fuel
cells (MFC) for powering the micro-electronic devices, bio-fuel cells (BFC),
which uses micro-organisms as the catalyst for the redox reaction and solid
carbon fuel cell (DCFC) in which solid carbon can be used as the fuel. The
electrochemical reaction of different fuel cells, the nature of the electrolyte and
the fuel used in the important types of fuel cell are schematically presented in
Fig. 1.Details of a typical PEM based fuel cell are presented in Fig. 2. In
addition to the fuel cell stack composed of several single cells (number
depends on the desired power to be delivered) a fuel cell power source
consists of fuel tank (with or without reformer), source of oxidant (air or
oxygen), power conditioner (DC/AC convertor) waste heat exchanger,
exhaust system etc. The schematic layout of such a power plant is presented
in Fig.3. Summary of the characteristics of the important types of fuel cells,
their operating conditions and application potentialities are presented in
atabular for in Table 1.

and High Temperature)
3.1 International Activity:
Among the various types of fuel cells, PEMFC is reported to have
reached acceptable level of technology development. These developments
have come from changes made from originally developed poly
tetrafluoroethylene (PTFE) bonded electrodes to direct transfer method to use
of some proprietary processes such as nano structured electrodes and
membrane. The maturity level is also indicated by the reduction in spending
on R&D by companies in advanced countries on this type of fuel cells. Bulk of
the R&D spending in recent times is on improving the manufacturability of
these systems. PEMFCs have been demonstrated in a variety of applications
(portable, stationary and transportation). In a report published in 2009-10, by
Pike Research, USA, it is stated that the stationary fuel cell market
experienced 60% year-over-year growth in unit shipments between 2009 and
2010. The Clean-tech Market Intelligence (another US based consultancy
firm) forecasts that sales volumes will continue to expand at an impressive
pace over the next several years, surpassing 1.2 million units annually by
2017. In a new report published in 2012-2013 from Pike Research the number
of stationary fuel cells shipped annually will grow from 21,000 in 2012 to more
than 350,000 by 2022. The Navigant report also indicates that over the past
year, the stationary fuel cell industry has experienced healthy growth due to a
surge in U.S. and foreign governments’ interest in reliable and resilient energy
sources. The sector is now at a point where, if, all government policy relevant
to stationary fuel cells was carried out, the global market potential would
surpassed 3 GW in 2013, and increasing to more than 50 GW by
2020. Further as per Pike research, nearly 2.5 million telecom towers will be
supported by fuel cell based back-up power system across the globe by 2020.
According to The Fuel Cell Today Industry Review 2012, PEMFC
dominated in terms of unit shipment in 2011, because of its usefulness in
diversified market segments most notably in small stationary and in
transportation applications as well as in consumer electronics applications
(DMFC). The growth was 87.2% (cf. 2010). Attempts to reduce the cost
component of platinum commonly used as electro catalysts in these fuel cells
are being aggressively pursued. In a major project launched in Canada in
2012, which involves several industries and with $8.1 million funds aims to
reduce the platinum content by 80% in automotive fuel cells. The first
prototype is expected to be ready in 5 years. In Japan N. E. Chemcat, a
catalyst manufacturing company is reported to have plans to acquire the core-
shell catalyst technology with ultra-low platinum from Brookhaven National
Laboratory for use in electric vehicle. Toyota Motor Corp., the biggest seller of
28
hybrid cars announced in 2010 that it had cut expenses to make the vehicles
by reducing platinum use to about one-third the previous level. Toyota and
GM now use about 30 grams of platinum per fuel-cell vehicle and aim to
reduce it to about 10 grams. Although alternatives are being investigated,
platinum would continue to play a significant role in PEMFC owing to its high
activity and durability. Green recycling methods to recover platinum are also
being pursued for sustainability. A UK project ($7.2 million) involving Johnson
Matthey Fuel Cells was launched in February 2012 to find methods for the
recovery of high-value materials from membrane electrode assemblies
(MEAs). Optimization of stack size for specific end use is another method
being researched for cost reduction e.g. the Japanese Ene–Farm program,
which used 1 kW PEMFC stacks originally are being reduced to 750 watts,
which is considered a better for Japanese homes.
Development of HT-PEMFC continues but with only a very small
number of commercial deployments so far. A large number of papers are
being published on high temperature membranes many of them without any
convincing results. In a recent paper, researchers in Japan have developed a
novel PEMFC that shows high durability (>400,000 cycles) together with high
power density (252 mW/cm2) at high temperature of 1200C under a non-
humidified condition. In order to prevent acid leaching from the HT-PEMFC
system, this group used poly(vinylphosphonic acid) (PVPA) in place of PA
because PVPA is a polymeric acid and is stably bound to the PBIs via
multipoint acid-base reactions.
Fuel cell Energy, USA demonstrated a HT-PEMFC System (540 kW
with ATR and logistic fuels) for ship board power generation in 2009. This
system used phosphoric acid doped PBI. In 2007, Volkswagen reported some
of their work on HT-PEMFCs for transport application. Enerfuel in Denmark
has demonstrated a 3 kW HT-PEMFC. Dantherm is reported to be developing
a 5 kW HT-PEMFC for telecom applications. Leaching of electrolyte and thus
durability has been a major concern. A power density of 100 mWcm-2 at
1600C was obtained when using a commercial HTPEMCELTEC-P1000 MEA
produced by BASF. Global Energy Corporation Inc, GEI, is another company
which has developed a 500 watts HT-PEMFC stack using BASF membrane.
Dominovas Energy’s Fuel cell division has also reported to be working on HT-
PEMFC. Advent sells small size membranes for high temperature fuel cells.
Helbio S.A. in Patras, Greece has received an order from a major Greek
telecommunications company for a 5 kW Fuel Cell Power System operating
on commercial propane. The system will be equipped with a HT-PEMFC and
will be designed for unattended system operation in remote location without
the need for external power input.
29
DoE, USA has set several technical targets for the membrane, catalyst
coated membrane for both stationary and automobile applications of which a
very few of them have been met so far.
All the major automotive manufacturers have a fuel cell vehicle either in
development or in testing. New models are being introduced regularly.
According to a report published by Pike Research, USA, a part of Navigant’s
Energy Practice published in 2009, the global commercial sales of fuel cell
vehicles (FCVs) will reach the key milestone of 1 million vehicles by 2020,
with a cumulative 1.2 million vehicles sold by the end of that year generating
$16.9 billion in annual revenue. The fuel cell car market is now in the ramp-up
phase and commercialization is anticipated by automakers to happen around
2015. Pike Research’s analysis indicates that, during the pre-
commercialization period from 2010 to 2014, approximately 10,000 FCVs will
be deployed. Following that phase, the firm forecasts that 57,000 FCVs will be
sold in 2015, with sales volumes ramping to 390,000 vehicles annually by
2020. The growth trends in Asia-Pacific region are going to outcast the North
America and the Western European regions. This large demand is expected
in the countries like Japan, Korea, China and India. Bulk of fuel cell vehicles
use PEMFC and most have hydrogen stored in composite cylinders.
Honda and Toyota have already begun leasing vehicles in California
and Japan. Seven major global automotive OEMs – Daimler, Ford, GM,
Honda, Hyundai, Nissan, and Toyota have co - signed a MoU in September
2009, signaling their intent to commercialize a significant number of FCEV
from 2015. Hyundai Motor introduced its Tucson ix FCEV equipped with its
newest 100-kilowatt (kW) fuel cell system recently. Hyundai will test 50 new
Tucson ix FCEVs as part of the second phase of the Korean Government
Validation Program and plans to begin mass production in 2015. Nissan
showcased NewTeRRA Fuel Cell Concept at Paris Motor Show 2012: The
TeRRA is designed as an evolution of the company’s popular Juke and
Qashqai crossover SUVs. It has three electric motors, one to power the front
wheels and an in-wheel motor in each of the rear wheels; Hyundai-Kia Motors
also signed a MoU with key hydrogen stakeholders from the Nordic countries,
Sweden, Denmark, Norway and Iceland to collaborate on market deployment
of FCEVs.
Over the past six years, more than 20 cities around the world have, or
are currently, demonstrating fuel cell or hydrogen powered buses in their
transit fleets. Most demonstrations involve individual cities and transit
agencies, but some have been multi-city demonstrations. These include
Clean Urban Transport for Europe (CUTE) – Multi city demo (since
2003, Ballard powered buses have operated for more than 78,000
hours delivering over four million passengers to their destinations)
30
Ecological City Transport System (ECTOS) based in Reykjavik, Ireland
Sustainable Transport Energy Perth (STEP) programme in Perth,
Western Australia
Hydrogen Fuel Cell Buses for Urban Transport in Brazil
Japan’s Fuel Cell Bus Demonstration Programme
National Fuel Cell Bus Technology Development Programme (USA)
and
China programme – Multi city demonstrations.
Most demonstrations reported better than expected performance and
strong passenger acceptance. The buses performed well across a wide
range of operating conditions: Hilly and flat terrain, hot, and cold temperatures
& high and low-speed duty cycles. Bus availability, an indicator of vehicle
reliability, was greater than 90% in many programs (CUTE, ECTOS, STEP,
and HyFLEET fuel cell bus trials). This was higher than expected. There were
no major safety issues over millions of miles of vehicle service and thousands
of vehicle fueling. The drivers preferred fuel cell buses to CNG or diesel,
noting their smooth ride, ease of operation, strong acceleration, and ability to
maneuver well in traffic. Fuel cell bus drivers were less tired at the end of their
shifts, mainly because the buses produced significantly less noise than diesel
or CNG. 75% of surveyed passengers reported a quieter ride. Most
participants found that the buses were easily incorporated into revenue
service, with some accommodation for increased vehicle weight and height
and longer fueling times. Most participants noted that developing fuel cell bus
maintenance facilities was not as challenging as expected. The current CHIC
(Clean Hydrogen In European Cities) project is building upon previous work
by the CUTE and Phase 1 of CHIC plans to roll-out a total of 26 buses across
four countries: London (UK), Oslo (Norway), Milan and Bolzano (Italy), and
Aargau/St. Gallen (Switzerland). In London, five buses are already in
operation and Transport for London (TfL). Similar programmes are being
executed in USA, Canada, Japan and China. Toyota Motor Corporation
(TMC) and Hino Motors, Ltd. (Hino) are planning to Provide Fuel-cell Bus for
Tokyo Airport Routes.
Another application area for PEMFC, which is expected to boost the
revenue of the fuel cell companies, is the fuel cell powered material handling
equipment for large warehouse operations. Several demonstration
programmes have already shown a cost benefit and convenient hydrogen
refueling. Fuel cell based forklifts have been employed in warehouses and
distribution centers. USA is the world leader in deployment of fuel cell based
forklifts and more than 1500 units have been deployed at various locations.
Fuel cell stacks of various capacities are deployed in forklifts.
Hydrogenics - 12 kW fuel cell hybrid power packs into two Hyster Class
forklifts.
31
Nissan (2006) - 9 kW PEM fuel cells using compressed hydrogen as
the fuel.
Tropical Green technologies -10 kW PEM fuel cell stack / MH system
Toyota Industries Corporation – 30 kW fuel cell stack and can lift a
maximum of 2,500 kilograms.

OorjaProtonics’ OorjaPacs a methanol-fueled fuel cell that continuously
trickle-charges an onboard battery, while the unit is in operation or
parked, have also been demonstrated in several fuel cell based
forklifts.
Noveltek, Taiwan has developed a forklift in collaboration with Nan-Ya.
Another niche area for PEMFC application is use in locomotives. In a
recent development in Denmark, a Hydrogen Train Project has been
announced which would use 150 kW PEMFC stack. In South Africa, Anglo
American Platinum Limited along with its project collaborators Vehicle
Projects, Trident South Africa, and Battery Electric, unveiled its fuel cell-
powered mine locomotive prototype using a Ballard Power Systems fuel cell.
The partnership will construct five fuel cell locomotives to be tested for
underground use at one of Anglo American Platinum’s mines.
PEMFC are also being tested for application in aerospace industries.
The application domain includes novel on-board systems, truck auxiliary
power units (APUs), ground power units, primary and emergency power, road
vehicles, and gate handling equipment such as conveyors, fuel trucks,
catering vehicles, water trucks, and mobile lighting, on board energy systems
for aircraft, galley operations, in-flight entertainment, peak power, and other
applications. In military the application include power for engine restart; on-
ground Heating, Ventilation and Air Conditioning (HVAC); electric and
pneumatic power; and cargo door operations. Fuel cells may also represent
the best alternative for efficient processing of bio aviation fuels presently
under development. Boeing and Japanese aircraft engine manufacturer IHI
Corp researching regenerative fuel cells to power aircraft electrical systems.
The in-flight testing was expected by the end of 2013. The companies
anticipate FCs could be used on aircraft as early as 2018, reducing amount of
jet fuel used for power generation by ~14%. Boeing Fuel cell airplane
demonstrator developed by Boeing Research and Technology ( B,R&T),
Europe which uses 20 kW PEMFC from M/s Intelligent energy has been
successfully tested. Boeing has long term plans for fuel cells, which besides
using PEMFC presently include use of HT-PEMFC and SOFC in the long run.
Airbus industries along with German Aerospace Center
32
(DeutschesZentrumfürLuft- und Raumfahrt; DLR) have also demonstrated fuel
cells in some applications. In one of its efforts, use of a fuel cell-powered
electric nose wheel, this will save fuel while significantly reducing airport noise
has been developed. The fuel cell-powered electric nose wheel reduces the
emissions produced by aircraft at airports by up to 27%, and noise levels
during taxiing by up to 100%. Aircraft fitted with this nose wheel will be able to
approach their apron locations travelling in both forward and reverse
directions, as well as taxi to their take-off positions without needing towing
vehicles or using their main engines.
There are reports of plans to use of fuel cells in Green Sea Ports. The
type of application envisaged are on-board ship power, a fuel cell system
could generate prime power or could propel the ship into port at low speeds
prior to docking. In addition, fuel cells could replace batteries and diesel
generators used for emergency power and on-board electronics, shore power
for cargo and cruise ships (auxiliary diesel engines that provide power to
docked ships contribute heavily to the pollution levels at ports). Fuel cell can
replace these diesel engines. FCEVs can replace yard tractors, heavy-duty
trucks, and passenger cars used at the port facility. Fuel cells can also be
installed as APU on heavy-duty trucks, to supply grid-independent power and
backup power for security, rail transport (fuel cells can be used as auxiliary or
primary power in rail locomotives), refrigeration for containers (the contents of
some containers need to be kept at a controlled temperature) and container
cranes (the offloading of cargo from docked ships is typically powered by a
diesel engine generator near the top of the crane or, more commonly, by
electric power onshore. A fuel cell could replace or supplement either).

3.2 National Status
The last few years has seen considerable research activity in hydrogen
fuel cells in India mainly via R&D work sponsored by the MNRE, DST, CSIR
etc. PEM Fuel cell uses a large range of materials. Such materials are electro
catalysts, catalyst support, gas diffusion media, micro porous materials,
hydrophobic materials, hydrophilic materials, different types of carbon and
binders, electrolyte, sealants, conducting coating materials.
The R& D activities encompass a wide variety of issues including
developing novel materials, durability, modeling etc. However there are very
few organizations involved in stack and system developments. The number of
Indian industries engaged in developing fuel cell technology in the country is
also few, although many have international collaboration for application
demonstration. A brief status and nature of work being done by various
organizations are given below:

3.2.7 Technology Demonstration
1. SPIC Science Foundation was the first institution in India to have
developed and demonstrated PEMFC in different applications. In 2000,
SSF had demonstrated fuel cells in UPS and transport applications. They
had developed complete process know-how for most of the components
used in PEMFC. Few years back they demonstrated 5 kW UPS based on
PEMFC. However, this group is not active presently.
2. BHEL R & D Developed a 3 KW PEM Fuel cell stack comprising of 1 kW
modules and demonstrated the same at BPCL. Recently they have
initiated work on HT-PEMFC using commercial MEA and also
indigenously developed membrane. Their experience in PAFC would be
highly useful in these developments. By September 2013, BHEL R&D
had planned to develop several 1 kW HT-PEMFC.
3. A CSIR Team comprising of CSIR-CECRI, CSIR-NCL and CSIR-NPL
have been jointly conducting research on PEMFC development and
developed a self-supported 1 kW fuel cell stack using many indigenously
developed components. The technology for one of the components
(carbon paper) has been transferred to an Indian Company. Besides
developing the main components of PEMFC the programme also focused
on measuring the performance of the components in single cells and in
stacks. Performance of MEAs is comparable to commercially available
MEAs. This team also developed and demonstrated a 250 Watts HT-
PEMFC stack built with several indigenously developed components.
Besides technology development, fundamental research by the team in
41
the areas of electro catalysis, membrane science, carbon materials and
stack engineering has resulted ~ 50 papers in journals of high impact
factors, completion of 12 PhD dissertations and filing of 10 patents by the
team across the three laboratories. Novel ideas on hybrid catalysts for
oxygen reduction reactions, new PBI copolymers, non-infringing routes to
synthesis of PBI monomers, new gas diffusion layers of high conductivity
and porosity and stacks of improved pressure distribution have been
developed.
4. Based on the developments summarized above, CSIR is setting up a test
bed for demonstrating and validating 3 kW LT-stacks for targeting a
PEMFC based back-up power supply for telecom towers. Reliance
Industries Ltd (RIL) is major industrial partner in this activity. Recent
research has shown that the performance of the HT-MEA developed in
CSIR is superior to the performance of commercial HT-MEAs. CSIR has
created strong IP portfolio in this area and the team will work towards the
demonstration and validation of a 1 kW HT-PEMFC stack based on
indigenous MEAs. In the near future, CSIR will create an Innovation
Centre on fuel cells in order to consolidate its resources and activities in
this area. The Innovation Centre will focus on R&D to develop the next
generation PEMFC systems, application development and vendor
development. It will strengthen the consortium of industries with a view to
demonstrate applications and establish manufacturing base within the
country.
5. IIT-M has demonstrated a bicycle powered by imported PEMFC.
6. VSSC, Thiruvananthapuram is reported to have developed a PEM fuel
cell using metallic bipolar plates. A major developmental programme is
also being planned.
7. NMRL has developed membranes for use in HT-PEMFC, which are
being tested in stack.
8. Centre for Fuel Cell Technology at ARCI developed and demonstrated
PEMFC in various capacities ranging from few hundred watts to 10 kW
modules. These stacks have been integrated with various balance of
systems. Grid Independent Power Supply systems in the range 1 kW to
20 kW have been developed and demonstrated. Recently the Centre
completed a 20 kW PEMFC system demonstration. CFCT has also
demonstrated their fuel cells in transportation applications as a range
extender in 3 wheeler and 4 wheeler electric vehicles along with battery
banks and has developed a fuel cell powered “Go-kart”. CFCT-ARCI has
developed process know-how for most of the components of fuel cell and
42
several balance of systems including controls and power converters. The
technology for making bipolar plate was transferred to an industry.
Besides these technology developments, the scientific personnel at
CFCT-ARCI have published nearly 80 papers in international journals
and have filed 20 patents.
9. DRDO is developing PEMFC power system for submarine application. In
the initial trails stacks from Ballard will be used.
10. DSIR has sanctioned a project to M/s ELPROS to develop PEMFC
systems.
11. NEAH Power Systems, Inc., a leading company in the development of
fuel cells for the military and portable electronic devices announced that it
has signed a letter of intent to explore acquisition or merger plans with
EKO Vehicles of Bangalore, Private Limited, India.
12. Nissan Renault operates a R&D centre working on PEMFC in Chennai.
13. GM R&D India Science Lab., GE’s John F Welch Technology Centre &
Mercedes-Benz Research & Development India Pvt. Ltd. (MBRDI) is
reported to have some hydrogen R&D programs in Bengaluru.
14. Other major PEMFC developers like Hydrogenics is also reported to be
interacting with some Indian Industries.
3.2.8 Industry Activities
The Indian Industries participation continues to be lukewarm. Some
companies are involved in demonstration notably in telecom sector. Hydrogen
supply is the major bottle neck that is hampering large scale deployment of
fuel cells in the country. By-product hydrogen from chlor-alkali units is being
targeted by many groups. However, this source can be counted to only a
limited extent for fuel cell applications as there is huge demand for this
hydrogen from different industries. The activities reported are summarized
below:
1. Tata Teleservices alongwith US based M/s Plug power made efforts for
installing and maintaining fuel cell systems as back-up power supply for
telecom towers. The other partner was M/s Hindustan Petroleum
Corporation Limited (HPCL). A few systems were installed in India. Later
M/s Plug Power decided to be in the area of application of fuel cell in
forklifts only and withdrawn their activities from India.
43
2. ACME Telepower Group had a tie-up with Canada based M/s Ballard
Power systems and M/S Idatech for fuel cell installation in telecom
sector. As per latest developments M/s Ballard has taken over M/s
Idatech and have tie-up with Dantherm. Dantherm are reported to be
working with Delta and installed 30 fuel cell systems in various telecom
towers located in Madhya Pradesh in association with Aditya Birla group.
3. Intelligent Energy, UK has started a business in India and planning to
install several PEMFC in telecom sector.
4. Altergy and ReliOn are also targeting India for fuel cell application in
telecommunication towers.
5. Electro Power Systems, based in Turin, Italy, launched its ElectroSelfTM
UPS product in India in December 2010. The ElectroSelfTM is a self-
recharging backup power system integrating a fuel cell and electrolyser
and requiring only minimal maintenance in the form of a water top-up
once a year. The company installed two systems for demonstration.
6. IOC R&D besides setting up the hydrogen fuelling station has also
planned to create fuel cell testing facilities, which would help in
establishing the country specific regulations, codes and standards
through the validation of testing procedures and measurement
methodologies for the performance assessment of fuel cells. It will also
have a reference function in the Indian Hydrogen Energy Roadmap for
pre-competitive research and performance verification. By building a
state-of-the-art fuel cell testing facility, Indian Oil R&D will have a foot-
hold in framing the fuel specification, infrastructure requirements, and can
facilitate the development and harmonization of fuel cell testing
procedures in transport and stationary applications considering the Indian
conditions. The facility may allow the comprehensive testing and
performance evaluation of PEM & solid Oxide fuel cells, stacks and
systems in terms of energy efficiency, durability, reliability and emissions
at a scale of up to 100 kW.
7. IOC is planning to have PEMFC based fork lift for demonstration at R&D
centre. Further, they have signed MOC with Tata Motors for joint
demonstration of FC buses to ply in the Faridabad region.
8. Tata Motors are reported to have developed a range of hydrogen fuel
cell-powered buses and light trucks. TATA and ISRO are partnering a
fuel cell bus demonstration programme in India using Ballard Fuel cell
stacks. The first vehicle was displayed at the Auto Expo in N. Delhi in
2012. IOCL and TATA Motors are reported to be establishing a hydrogen
44
fuelling station in Faridabad in Haryana to demonstrate two fuel cell
buses developed by Tata Motors, which uses fuel cell stacks from M/s
Ballard. They are also planning to set up a major hydrogen dispensing
station at Sanand, Gujarat for the technology demonstration of the fuel
cell buses being developed by them.
9. REVA electric Car Company has demonstrated fuel cell powered
passenger car using Ballard stacks.
10. Reliance is reported to be the industrial partner in the NMTLI project
with Team – CSIR
11. M/s Falcon Graphites, a small scale company in Hyderabad has
commenced large scale production of bipolar plates based on technology
developed by CFCT-ARCI.
12. The technology for carbon paper developed by NPL has been transferred
to HEG Limited Noida, which is expected to begin production soon.
13. M/s Arora Matthey, Kolkata has been a major supplier of electro catalysts
in India.
14. Sai Energy in Chennai is becoming a major supplier of fuel cell materials
and components.
15. Sai Energy, Chennai is also reported to be partnering Tata Chemical
Innovation Centre (TCIC) in developing fuel cell stacks, which use
catalysts developed by TCIC.
16. Sai Energy-Anabond consortium in Chennai is reported to have joined
hands with Team-CSIR for demonstrating PEMFC stacks in different
applications.
17. TCIC is working to develop a non-nafion / or substantially reduced use of
nafion MEA part of PEMFC, aiming to develop both novel catalyst and
membrane to decrease the cost of MEA to an affordable level for
stationary applications. TCIC in short duration has developed the 500 W
stack and aimed to develop 5 kW stack in 2013 mainly using own
catalyst and other locally available FC components as prototypes for field
trial at telecom tower for testing their durability & stability using hydrogen.
18. M/s Thermax, Pune may soon enter into an agreement with NCL &
CECRI (CSIR) for prototype manufacturing of HT-PEMFC to be used in
45
combined cooling and power (CCP) mode based on a vapour adsorption
technique.The targeted capacity of the stack is 5kWe.
19. M/s KPIT Technologies, Pune is in the process of making an agreement
with NCL (CSIR) to develop LT-PEMFC stacks of 8-10kW capacity for
application in automotive in which fuel cell power will be supplemented by
a combination of supercapacitors and lithium ion battery and the fuel will
be enriched with oxygen.
3.3 Gap Analysis & Strategy to bridge the gap
3.3.1 Gap Analysis
Globally, PEMFC has numerous applications including stationary
power generation (centralized and decentralized), transportation
(automobiles, railways, aeroplanes, ships), back-up power supply (telecom
towers, residences, commercial places), material handling applications
(forklifts for warehouses and locomotives for mines), auxiliary power units for
trucks, locomotives, aeroplanes, ships) portable applications (lap top charger,
mobile charger) and micro-power supply to electronic equipment. New
applications are continuously on increase. According to Fuel Cell industry
Review in 2011 around 2,77,700 units of PEMFC were shipped by various
countries.
A number of industries in USA, Canada, UK, Germany, Australia,
Japan, Italy etc. are manufacturing these products for various applications
and meeting the domestic demand and exporting their products to various
countries. Further as per Pike research, the number of stationary fuel cells
shipped annually will cross 3,50,000 numbers by 2022. Power supply system
used in 25 lakh telecom towers will be converted to fuel cell based power
system across the globe by 2020. It is expected that potential of global
market for stationary fuel cells will reach to 50 GW by 2020. These countries
are exporting the various products based on PEMFC to all over world. All the
major automotive manufacturers have a fuel cell vehicle either in
developmental or in testing stage. Pike research analysis indicates that
57,000 fuel cell vehicles will be sold in 2015, which will increase to 3,90,000
vehicles annually by 2020.
In India, research institutions are more focused on materials
development and modeling, whereas CSIR, DST,defence and space research
laboratories are engaged in the development of complete PEMFC including
46
stacks. However, some labs are reported to have imported fuel cell stacks for
carrying out integration studies. Demonstration of PEMFC requires large
number of stacks at reasonable cost. No engineering efforts have been put for
the manufacture of stacks / systems so far (Except PAFC stacks by Thermax
particularly for the strategic sector for which economic consideration has not
been an important parameter). There is still no mechanism in place to make
large number of stacks / systems for demonstration on a large scale so as to
establish an optimized manufacturing technology. In addition, hydrogen is
also not available at reasonable cost to run continuously these stacks /
systems, which are being researched / demonstrated. Testing of fuel cells at
sites, where hydrogen is easily available such as chlor-alkali units, is urgently
required to make further improvements in the indigenously developed
systems. The chlor-alkali units are not very warm to this idea. In addition,
compact reformer development (methanol / natural gas / LPG) in the country
has not taken place. Several groups have developed catalysts for such
reformation and also for PROX and other purification chains. NMRL is
reported to have developed a fuel reformer, but is not available to others.
Some institutions are reported to have imported small capacity reformers and
are in the process of integrating the same with fuel cell stacks. The cost of the
imported reformer is very high.
Several membranes are reported to have been developed in the
country. However, most of these membrane developments are restricted to
small size membrane with the notable exception of the membranes (PBI
membrane for HT-PEMFC, Nafion composite membrane for LT-PEMFC and
membrane for DMFC) developed by a few national laboratories. The process
of making these membranes is still manual and only small sized sheets can
be made. No long term testing of these membranes in fuel cells has been
reported from Indian Laboratories. A large number of catalysts have been
developed in the country and tested in half/single cell. However, the
laboratories engaged in fuel cell stack development are using standard
commercial catalysts. Bipolar plates have also been developed indigenously
by CFCT-ARCI, CSIR lab and VSSC and technology has also been
transferred to Industry by CFCT-ARCI.
HT-PEMFC seems more promising than LT-PEMFC, as they can
tolerate more CO impurity in the hydrogen feed and can be useful in CHP/
CCP applications. It has many potential drawbacks including increased
degradation, leaching of acid and incompatibility with current state-of-the-art
fuel cell materials. In this type of fuel cell, the choice of membrane material
determines the other fuel cell component material composition. Novel
research is required in all aspects of the fuel cell components so that they can
meet stringent durability requirements for various applications. Selective
research should be supported with tangible goals.
47
There is an urgent need to initiate projects in mission mode on stacks /
systems building and their demonstration involving academic institutions to
address specific issues. The project should aim to identify Indian laboratories
to scale up these materials and building stacks/complete system. A clear
distinction needs to be made between academic research and applied
research with suitable funding for the applied research. There is a need for
aggressive research programs with more thrust on applied research, analysis
of the achievements in materials developed so far and take forward the
promising ones to large scale preparation. It should focus on performance
improvement at the systems level and take up programs with multiple partners
(intra or inter institutions) with interlocked objectives/tasks. These institutions
should initiate major programs on stack assembly engineering & system
integration using available materials and understand the dynamics. Major
programs should be started on BoS development (air moving devices, thermal
management devices, motors, pumps, all with low power requirement, high
efficiency inverters and converters), system development and integration of
the components. Merit of such programs should include power density at
given cost, weight, lifetime and manufacturing R&D for fabrication of repeat
components.
3.3.2 Strategy to Bridge the Gap
3.3.2.1 Basic Strategy
LT-PEMFC technology has been demonstrated but durability studies at
component and long term performance of the cell have not carried out. Most
of the results reported are based on electrochemical studies. Only a few
groups are working on stack and system development. Efforts for the
manufacturing R&D were not made. Large number of research groups
engaged in hydrogen research and trained man power availability is on the
increase. System level development is very low. Hydrogen infrastructure is
very poor. Financial support for basic research is high, which needs to be
necessarily linked with applied research / technology development. Industry
participation is poor. With increased demand on energy requirement for both
transport and stationary power, business opportunity is high and scope of
advanced R&D as well. Further delay in technology development will lead to
International players flooding their products in Indian market, legging behind
the domestic industries. Research may be continued for the development of
low cost durable membranes, increased tolerance for impurities in feed,
reduction in catalyst cost, improvement in durability and performance
improvement of low temperature and high temperature PEMFC. Thus, there is
need for vertical research instead of horizontal research. FocusedR&D may
be initiated under the following areas:
48
High-throughput catalyst synthesis and basic characterization
Reduction in catalyst loading on electrodes
Manufacturing processes and materials for fuel cell systems.
Development of diagnostic techniques to help optimize cost/lifetime of
fuel cell systems to aid commercialization
Low-cost purification systems for hydrogen reformers
Accelerated life testing of components and systems
Standards and regulations related to deployment of systems
Design scalable, high-throughput fabrication processes for high-
performance MEAs.

tolerance to air, fuel and system-derived impurities) and improve
durability with cycling
Develop sustainable MEA designs that incorporate recycling /
reclamation of catalysts and membranes and/or re-use of cell
components.
Non-noble metal catalysts in combination with new hydrocarbon

49
Transient tests for accelerated load profiles
o Continuous idle to full load tests
o Continuous half load to full load tests
o Fast deceleration tests
Investigating the electrical, thermal and environmental performance of
the fuel cells over a wide range of power loads
3.3.2.2 Identification of the application areas
PEM fuel cells (LT-PEMFC and HT-PEMFC) are ideally suited for
application requiring less than 100 kW in stationary / distributed power
generation. The quick start-up and low temperature operation of LT-PEMFC is
ideally suited for strategic sectors. The stationary application does not require
stringent volume / weight issues normally associated with transportation
application. Initial application could be in niche areas such as
telecommunication towers in remote areas. Currently, back-up power to these
towers is provided by batteries for the short-duration and noisy and low-
efficiency DG sets for long duration. In some locations where there is no gird
connectivity, they are run completely on DG sets. With the Telecom
Regulatory Authority of India (TRAI)’s directive of 2012 is to power 50% of all
rural telecom base station towers and 33% of all urban towers in the country
by hybrid solutions within 5-years, there is a huge impetus for the deployment
of fuel cells for such applications. Hybrid solutions involve a combination of
renewable energy sources, such as hydrogen fuel cells, and grid electricity.
Natural extension is to IT companies, hotels, shopping malls, remote
areas like meteorological stations eventually reaching common households as
back-up power units.
PEMFC is ideally suited for transportation application. However fuel
cell stacks for transportation application requires meeting stringent size and
weight targets. The first step could be to develop PEMFC for application
Materials handling Devices such as forklifts. The specification targets for this
application can be met. Application in transport especially cargo handling
trucks (Small, Medium, Large) could be the next application followed by use in
buses. The other applications may be in refrigerated trucks for dairy products
/ short life food commodities, sea ports and rail yards.
Other niche areas like airports, sea ports can also be addressed.
3.3.2.3 National Targets
The success of achieving the targets depends on selecting the projects
for support for development of PEMFC (LT-PEMFC and HT-PEMFC) in India.
50
The funding agencies should consider calling for proposals for specific
development instead of total fuel cell stack development alone. This would
bring in more working groups. Special attempts should be made for the
development of fuel cell stacks for transportation application. If possible a
distinction needs to be made between these two application regimes and
thus the targets. Projects should be initiated on developing test benches for
use in evaluating the fuel cell stacks. Presently, most of the project proposals
include cost of an imported test bench which constitutes a substantial part of
the project cost. The following targets can be set for development of PEMFC
(LT-PEMFC and HT-PEMFC) systems for different applications:
(i) Capacity vis-à-vis Application Targets
Telecom towers 3-5 kW
Urban households 1-5 kW
Small trucks 3-10 kW
Medium trucks 10-15 kW
Large trucks 25 -50 kW
Submarine application and buses 50-120 kW
(ii) Development Targets
Different groups in the country have already demonstrated up to 25kW
of LT-PEMFC stacks whereas for HT-PEMFC the development, including the
membranes, is mostly at its initial stage. Not more than 1kW stack has been
demonstrated so far. However, considering the advantages of HT-PEMFC
over the LT-PEMFC particularly in terms of higher CO tolerance by the former
and the possibility combined heat and power or combined cooling and power,
it is proposed to pursue the development of HT-PEMFC more aggressively
than LT-PEMFC in this country. Accordingly, the following time targets may be
fixed for the development and deployment of these fuel cells:
Fuel Cell
Type
Phase-I (2016-
2018)
Phase II (2019-
20)
Phase-III (2021-
2022)
HT-PEMFC
Up to 5kW Up to 25kW Up to 50kW
LT-PEMFC
Up to 25kW Up to 50kW Up to 120kW
The efficiency target may be 37-40% for the phase-I, which may be
enhanced to ~50% by the end of phase-III.
51
All the units should be capable of cold start down to a temperature of at
least -20oC.
Precise cost targets are difficult to be fixed at this stage. However, an
approximate cost target of Rs.2.5 lakh/kW for LT-PEMFC systems of more
than 5 kW capacity with a durability of 5000h (stationary application) could be
aimed at during the first phase. The system should comprise of stack, air
supply units, thermal and humid units, power electronics, sensors and control
units using a maximum of 30% imported components. In the second phase,
the target may be Rs.2.5 lakh/kW with completely indigenous components.
However, the ultimate target at the end of Phase-III could beRs.50,000/kW,
with adaptation of best practices in manufacturing. One of the global
projections based on a very high volume production (500,000 units per year)
is as follows:
Fig. 7: Cost Estimate of PEMFC Fuel Cells over the years.
Another very important criterion is the power density of the stack. The
target may be 1kW/L during the first phase to be enhanced to 2kW/L at the
end of phase-III from the current level of ~200W/L.
In order to reach the targets mentioned above, several key materials
and components e.g. membrane, GDL, monomer dispersions, and catalysts
may continue to be imported, at least for some more time.Efforts need to be
put in to ease their import as well as enable their manufacturing in the
country, on an urgent basis.Importing of several key machines will also be
essential to proceed with automation to achieve the cost targets mentioned
above,

55
4.0 Phosphoric Acid Fuel Cell
4.1 International Activity
PAFC systems were initially developed for military applications in the
decade of seventies in USA. Spurred by the initial success, the technology is
further developed for commercial applications by companies such as M/s
UTC, USA. A packaged module of around 250kW using PAFC for power
generation with online reformer based on propane/LPG was tried in different
parts of the world. The technology was also used and further developed by
companies such as M/s Toshiba and M/s. Fuji electric Japan.
Commercial plants ranging up to several hundreds of kilowatts with a
fuel processor (reformer) are being developed and have shown PAFC life to
be more than 45000 operational hours and more than 85% availability of the
plant during its entire life cycle. These plants were accomplished using
CNG/LPG/ land fill gases as the primary fuel that got converted to hydrogen
rich reformer gas by the online fuel processor. Such commercial plants are
available for outright purchase and the units being modular may be easily
transported. Multiple units can be used to meet higher demand. The systems
developed are mainly for catering to base load onsite power generation and
can be operated continuously.
Companies such as M/s UTC have also developed a variant for
operating city buses with a PAFC unit along with methanol reformer as an
onboard Hydrogen source. The buses mounted with PAFC and reformer
systems were demonstrated successfully at Georgetown, USA.
4.2 National Status
Bharat Heavy Electrical Ltd. Corporate R&D has carried out lot of
research work in development of PAFC stacks. In this regard, a 2x25 kW unit
was developed and operated using Hydrogen from the Chlor -alkali industries.
Further, BHEL (R&D) procured a 200kW PAFC unit from M/s Toshiba that
uses LPG as the primary fuel and was installed and operated successfully by
BHEL (R&D) engineers. This activity was discontinued due to problem of
leaching of electrolyte (phosphoric acid) and maintenance issues.
Naval Materials research Laboratory (NMRL), Ambernath, one of
DRDO’s Naval cluster laboratories undertook a long term PAFC development
plan in the early nineties. Initial efforts focused on development of all
materials & related technologies necessary for PAFC technology, which was
then, transformed to willing industry partners. Accordingly, PAFC stacks
56
ranging from 1kW to few kWs have been developed and produced through
industry for tests & evaluation.
NMRL has also developed other accessories such as fuel processors
viz, compact, planar methanol reformers and Borohydride hydrolyzers
coupled with power electronics to feed conditioned power solutions for
defence applications. Products such as onsite, mobile/transportable power
generators ranging from 1kW to 15 kW were developed and demonstrated
successfully for field applications with very low signatures.
The laboratory has finally transferred the technology to M/s Thermax
Ltd, Pune,who have set up a manufacturing facility for PAFC based on a
technology developed by NMRL (DRDO)and have already manufactured and
supplied to DRDO (through a buy-back arrangement) 24 units of 3kW stacks
for their strategic applications. The facility is provided with all sub-
manufacturing modules to manufacture electrodes from basic raw materials,
assemble them in the form of fuel cell stacks and conduct elaborate testing of
each stack for meeting the strict quality control requirements of NMRL
necessary for defence establishments. A large scale skilled manpower for
manufacture of fuel cells is also being built in the process.
This is so far the only example of a successful indigenous
production of fuel units in India even though on a buy-back
arrangement.Presently NMRL is engaged in the development of underwater
power solutions together with improved versions of field powering for remote
and sensitive areas.
4.3 Gap Analysis and Technology Road Map
With the initiatives taken by NMRL and Thermax Ltd., India has already
taken the very first and the most important step for commercialization of fuel
cell technology in this country. Even though this particular type of fuel cell has
certain inherent drawbacks such as use of corrosive electrolyte together with
expensive platinum catalyst in relatively large quantities, the technology can
still be pursued in the country particularly for large capacity (MW scale)
distributed stationary power plants in the civilian sector till alternative fuel cells
of the same scale are available for deployment.
4.3.1 Identification of Potential Application Areas
Land based applications are distributed power for remote area,
sensitive location and tent city application. Marine applications are underwater
powering and all electric ship propulsion civilian spinoffs applications are high
57
efficiency power generators for distributed applications, Hydrogen grid area
powering, powering of large transport vehicles etc.
4.3.2 National Targets in next 10 years
(i) Land based distributed power systems for forward area power using
local energy harvesting with civil spinoffs:
(a) Broad spectrum fuel processor technologies viz, diesel
reforming, CNG/LPG reforming, Bio-ethanol reforming and direct
Hydrogen feed from solar/wind power systems including hybrids
with fuel cell power plants.
(b) Deployment of an aggregate of around 10 MW of PAFC field
generators of various capacities for defence applications, static
and field mobile platforms, distributed power generation.
(ii) Lowering of production cost with technology development for cheaper
components of the fuel cell plants to lower the PAFC cost to less than
Rs 30,000/kW inclusive of accessories.
(iii) Underwater and marine propulsion applications for defence use.
4.3.3 Technology Gaps
(i) Low cost PAFC catalyst: Research on development of low noble metal
content catalyst, structured inter digitated electrodes, improved
support etc.
(ii) Fuel processor technology for broad spectrum fuel: Technology for
compact diesel fuel processor along with multi-purpose reformers for
various fuels like Dimethyl ether (DME), ethanol, CNG etc.
4.3.4 Development Plan
The time frame for different capacities for PAFC systems may be as follows:
Fuel Cell
Type
Phase-I (2016-
2018)
Phase II (2019-
20)
Phase-III (2021-
2022)
PAFC Up to 50kW Up to 100 kW Up to 250 kW
(i) Primary technology development initiatives may be taken by DRDO
research groups through technical projects. These groups will be
responsible for the development of the basic technology.
58
(ii) In-house R&D will be carried out based on strong research areas and
core competence of DRDO. Research work as per requirement and
expertise will be outsourced to Indian Research organizations as sub-
projects.
(iii) Mature Technologies if available abroad will be assimilated through
technology transfer to DRDO project group or to DRDO nominated
industry partner as applicable.
(iv) Assimilation of technology for system development: A core group
inside DRDO to hold the know-how and know-whys of the
technologies developed and will be responsible for transferring the
technologies to Indian industries for realization of the products for the
user. DIITM at DRDO Hqrs in association with FICCI may be the
main interface with Indian Industries.
(v) Business plan to realize system is as per DRDO’s rule viz to transfer
the technologies to relevant industry through technical report, training
and support to develop the equipment and infrastructure. ToT fees
with commitment to effect supplies for DRDO & Indian Armed Forces
will be decided by DIITM.
4.3.5 Challenges towards PAFC Technology Commercialization
(i) High cost of production of PAFC is primary impediment towards its
commercialization.
(ii) The fuel infrastructure that is mostly for fossil fuel need to be
upgraded to enable renewable fuel usage. Additionally, fuel
processors to adapt fossil fuel to be inducted for operational flexibility
and better marketability.
(iii) There are various restrictions to use fuel cell power plants that need
expensive and complicated control systems. Rugged PAFC
technology with minimal operational restrictions needs to be
developed & commercialized to meet the market expectations.

SOLID OXIDE FUEL CELL

5.0 Solid Oxide Fuel Cell
5.1 International Activity
Research on SOFC has reached to a reasonably matured stage,
particularly in the advanced countries like USA, Canada, Germany, UK,
Denmark, Australia, Japan etc., where commercialization of the technology
seems to be viable through prototype demonstration as well as installation of
systems, particularly for residential and transport applications. The technology
development so far has been realized through major programmes such as
Solid State Energy Conversion Alliance (SECA), USA, Framework program
on SOFC (Europe), NEDO (Japan) etc. One of the key features of all such
programmes has been the industry-institute participation with clear cut
objectives and deliverables to achieve the final goal. As an outcome of these
programmes, several industries have built up their capabilities to develop the
technology. The following companies are active in SOFC development and
demonstration in recent years.
Westinghouse and Siemens were pioneers in SOFC development.
However there seems to no activity reported by these companies in recent
years. The prominent players presently are: Accumentrics, Bloom Energy,
Delphi, Protonex , Ultra Electronics AMI, Lockheed Martin, Versa Power,
FCE( USA), Ceres Power (UK), LG Fuel cell systems ( South Korea),
Elogenis, Convion/Wartsila (Finland), Hexis AG (Swiss), SOFC power
ApA,(Italy), Staxera-Sunfire, Germany, Topsøe Fuel Cell (Denmark), Kyocera,
Mitsubishi Heavy Industries (Japan), Ceramic Fuel Cells Limited (Australia).
Acumetrics with Sumitomo in Japan has developed micro tubular
anode supported SOFC. They have built 1 kW micro-CHP system for the
home. Bloom Energy has seen fastest growth in SOFC deployment. They
have already deployed a large number of SOFC systems (Planar design) in
100 kW range at Google, Coca-Cola and Bank of America and eBay. Bloom
Energy have some R&D and production activity in India also. Delphi is
focusing on SOFC solution (anode supported planar design) for APU
application in Volvo trucks. They are also participating in the Integrated
Gasification Fuel Cells Power Plant (IGFC) project with UTRC. Protonex,
which acquired Mesoscopic Devices LLC develops SOFC systems based on
tubular-cell technology for portable and mobile applications. Ultra Electronics
AMI is engaged in developing small SOFC systems in the power range 250-
300 watts, which operate on propane, butane and LPG. Lokheed Martins
program is on integrating SOFC with solar panels. Versa Power, which also
has Fuel cell Energy, a leading company in MCFC is working on SOFC-GT
systems with an ultimate aim of 250 kW and above with integrated coal
gasification. Ceres Power develops micro-CHP SOFC systems (metal
62
supported structures) for the residential sector and for energy security
applications. Elcogenics has demonstrated 1 kW IT-SOFC system, which is
based on anode supported cells. Hexisdeveloped planar SOFC-based CHP
units for stationary applications with electrical power requirements below 10
kW, which integrates a catalytic partial oxidation (CPOX) reactor. The cell
design is unique flow field design. The LG Fuel cell system (SOFC-μGT)
based on the technology from Rolls Royce technology is also being positioned
for use in integrated coal gasification plants with sizes greater than 100
MW.SOFCpower SpA develops anode supported SOFC (1 kW) for micro
CHP applications. The Staxera SOFC stacks (4.5 kW) use ferritic bipolar
plates and electrolyte supported cell configuration. Topsøe Fuel Cell, focuses
on the development of residential micro-CHP and auxiliary power units with
SOFC planar anode-supported technology (1-5 kW), Topsøe with Wärtsilä
have installed 20 kW SOFC, which uses land fill gas. They plan to scale this
to 250 KW system eventually. Convion/Wärtsilä are reported to have
developed and commercialized 50 kW and larger SOFC products for
distributed power generation markets. Kyocera is developing micro-CHP
systems (750-1000 watts) for ‘ENEFARM’ program and is collaborating with a
number of companies like Osaka gas, Toyota, JX Nippon Oil in these
demonstrations. Mitsubishi Heavy Industries has a long experience in SOFC.
They demonstrated a pressurized 21 kW SOFC in 1998. They also
demonstrated a SOFC-micro CHP (75 kW) in 2004, which has been now
scaled up to 229 MW. Their mono block technology with planar cell includes
internal reforming. Ceramic Fuel Cells Limited manufactures and markets
planar SOFC anode-supported technology systems for small-scale
cogeneration (1.5 kW). It is expected that 100.000 units will be delivered in
the next 6 years.
Lowering the operation temperature to around 500-800oC is one of the
major objectives of recent SOFC research activity. The main challenge is that
to develop cell materials with acceptably low ohmic and polarization losses to
maintain sufficiently high electrochemical activity at reduced temperature. The
nano scale engineering and nano-structured approached in the development
of high efficient and high performance electrodes in SOFC is a relatively a
new phenomenon. The nano composites will tremendously reduce the
working temperature of conventional SOFC from 1000oC to 300oC which
opens new opportunities and success by employing composites and nano
technology.
5.2 National Status
In India, there has been a spurt in SOFC research since the last
decade. The relevant research has primarily been catered by the academic
institutions and Government R&D organizations. However, there is a growing
63
interest among many private and PSU organizations which are initiating their
own R&D programmes. Though many institutions as listed in Table given
below may be considered to have research activities related to SOFC, these
activities have largely been limited to material development, except CSIR-
CGCRI, Kolkata and BARC, Mumbai, where efforts have been made to
develop the total technology with varying degrees of achievements.

CSIR-CGCRI, Kolkata has the strongest R&D group for technology
development in the area of SOFC, which was initiated in the mid 90’s. The
initial activities were focused on materials development. In recent years
stack development is given major thrust, which has resulted in the
demonstration of a 250 watts stack (anode supported , ferrite steel based
metallic interconnect) in 2011, followed by a 500 watts stack in 2013, and
1kW stack in 2015 using anew SOFC bi-polar stack design.
BARC is focusing on developing tubular SOFC. The R&D activities include
materials development by different routes, electrolytic coating by electro-
chemical vapor deposition (ECVD) process, dip coating, spray deposition
and electrophoretic deposition etc. The programme, however, is slowly
tapering down.
IIMT, Bhubaneswar is working on development of solid oxide fuel cells
(SOFC) using low-cost ceramic processing techniques like electrophoretic
deposition, slip-casting, dry pressing etc. They are developing a 1kW
65
stack. They are also developing alternative anode material, that is tolerant
to sulphur under the Indo-UK Fuel Cell Initiative Programme
NFTDC, Hyderabad in collaboration with Cambridge University is
developing metal supported SOFC and plan to build 1 kW stacks shortly.
CSIR-NAL started working developing materials and processes for the
tubular SOFC from 10th Plan. Anode supported button cells with a power
density of 350 mW/cm2together with tape casting process, interconnect,
sealant and test bench were developed. Recently, activities on fabrication
of self-reforming anode supported SOFCs for direct utilization of
hydrocarbon fuel and intermediate temperature SOFC have been initiated.
CSIR- NAL is in the process of transferring technology for the fabrication
of SOFC electrodes to some industries. Currently, work is focused towards
the development of a stack with 50 W power.
Materials of SOFC and IT-SOFC are being pursued at IIT-M [rare earth
doped zirconia and ceria, BaCeO3 based proton conducting oxides (PCO)]
, IIT-D ( anode supported SOFC, Cu-Co bimetallic impregnated in CeO2 –
YSZ cermet anodes , Yttrium and Lanthanum doped Strontium titanates) ,
Thapar University (of bismuth based cathode materials and lanthanum
based perovskite materials for the electrolyte applications, SiO2-BaO-ZnO-
M2O3-B2O3 (M=Al, Mn, Y, La) based glass sealants , SiO2-B2O3-MgO-
SrO-A2O3 (A=Y, La, Al) based glasses),
IIT Bombay and IIT Kanpur have also recently initiated SOFC activities on
new materials development along with simulation & modelling for planar
SOFC. International Advanced Research Centre for Powder Metallurgy
and New Materials (ARCI), Hyderabad has started working in SOFC on a
typical design of honeycomb structures for specific application. In addition
to R&D establishments, multi-national companies such as GE (India),
Bangalore and Bloom Energy (India) Pvt. Ltd., Mumbai have ventured into
this area, primarily to assemble imported parts supplied by their principals.
BHEL, CTI, Bangalore has initiated the research work with SOFC single
cell testing using their own developed glass based seals. NTPC has also
planned to initiate activities on SOFC. With respect to gasification of
Indian coal, Thermax Limited, Pune is involved in building a gasifier for
coal and biomass for quite sometimes and now looking for application of
bio gas in SOFC.
Thus, it may be commented at this point that through research
initiatives at various levels, the overall strength in the field, in terms of
knowledge base, skilled manpower and infrastructural facility, the SOFC
development has reached a degree of maturity where, at least, pre-
commercial trials is envisaged in near future through well-framed network
programmes involving R&D organizations, Academia and Industry.

5.3.1 Issues / Challenges for Commercialization of the Technology in
the Country
Necessary expertise and knowledge-base has been generated in the
country to a stage where development of the total SOFC technology seems to
be definitely feasible. However, for commercialization of the technology, there
are certain issues/challenges that need to be looked into. The following are
some of the key issues:
No concerted efforts have been made so far to develop the
technology under a national program involving institute-industry-
academia. Whatever successful commercialization has been
made so far in the advanced countries, are mainly through such
national programs (e.g. SECA in USA) only.
As SOFC technology is related to an alternate source of energy,
import of key component materials in future may be restricted
and/or become more costly
Global competition from various existing manufacturers,
particularly from China
Significant financial requirement for establishment of the
technology

5.3.2 National Targets
Considering several advantages of the technology, particularly in terms
of fuel flexibility, overall efficiency, possibility combined heat and power
utilization and the level of expertise available in the country, it is suggested
that the development of this technology should be taken up in the “mission

6.0 Direct Methanol / Ethanol Fuel Cell
6.1 International Activity
6.1.1 Direct Methanol Fuel Cell
In 1951, Kordesch and Marko identified for the first time the possibility
of using methanol as a fuel for fuel cell system. However, the major
developmental milestones for DMFC technology did not come until the 1960s.
At this time, methanol was being steam reformed to produce hydrogen which
was subsequently used in fuel cell systems. In developing DMFC systems,
researchers hoped to find a way of removing the reforming step and enabling
the direct use of methanol to produce electricity. In 1963, researchers at Allis-
Chalmers tested a methanol fuel cell which used potassium hydroxide as an
alkaline electrolyte. The degradation of the alkaline electrolyte by carbonate
formation was observed as part of this work and the theory of regenerating
carbonate ions to hydroxide ions was proposed. By 1965, both Shell and
ESSO had given much attention for the development of DMFC systems. Shell
chose to research the use of aqueous sulphuric acid electrolyte in favor of
alkaline electrolyte as this was unaffected by the carbon dioxide produced in
the electrochemical reaction. ESSO also produced a direct methanol-air fuel
cell which utilized sulphuric acid electrolyte. This system was developed for
the US Army Electronics Laboratories for use in portable military
communications equipment. Also in 1965, Binder developed catalysts for
DMFC technology based on noble metal alloys. In 1992, Jet Propulsion
Laboratory, Giner and the University of Southern California developed a
DMFC which operated with a Nafion membrane. The solid nature of the
membrane meant that it became necessary to deliver methanol fuel to the
anode rather than through the electrolyte as had been the case in the
sulphuric acid system. This new fuel delivery method thus began to resemble
the modern day design of DMFC technology much more closely.
DMFC are best suited to applications under 100 W. SFC Energy (SFC)
was one of the first companies to successfully commercialize a fuel cell
consumer product and the first to do so in the Auxiliary Power Unit (APU)
sector. Its range of DMFC products targeted at consumers, industrial users
and military users. OorjaProtonics offers a different approach to the Materials
Handling Vehicle (MHV) market: instead of replacing lead-acid batteries with
fuel cells, it offers DMFC charger that sits on top of the existing battery and
extends its operation. Direct Methanol Fuel Cell Corporation develops and
manufactures disposable methanol fuel cartridges that provide the energy
source for fuel cell powered notebook computers, mobile phones, military
equipment and other applications being developed by electronics OEMs, such
as Samsung and Toshiba, and other companies. DMFC Corporation has
72
licensed an extensive portfolio of direct methanol fuel cell patents from
Pasadena-based California Institute of Technology (Caltech) and the
University of Southern California (USC). DMFCC is partnered with Samsung
and other companies engaged in fuel cell development and applications.
Small, portable fuel cells for hand-held devices are being developed by a
number of companies. For instance, Toshiba (Tokyo: 6502 JP) has already
developed a direct methanol fuel cell for use in electronic equipment, which
they are currently integrating into several electronic prototypes, including
digital music players and laptop computers.
However, in order to be competitive within the transport market, the DMFC
must be reasonably cheap and capable of delivering high power densities. At
present, there are a few challenging problems in development of such
systems. These mainly consist in finding i) electrocatalysts which can
effectively enhance the electrode-kinetics of methanol oxidation ii) electrolyte
membranes which have high ionic conductivity and low methanol crossover
and iii) methanol tolerant electro-catalysts with high activity for oxygen
reduction. One of the biggest challenge is engineering a product.
6.1.2 Direct Ethanol Fuel Cell
One of the challenges in DEFC is the incomplete oxidation of ethanol
to produce hydrogen gas. Several studies have been reported that new
catalysts, which are better than the conventional catalyst, have been used in
DMFC. Scientists from California Institute of Technology, San Francisco,
USA developed direct ethanol fuel cell, which exhibit a power density of 110
mW/cm2 under extremely severe conditions (Nafion®-silica, 1400C., 4 bar
anode, 5.5 bar oxygen). A team of researchers from Brookhaven National
Laboratory, USA and University of Delaware have synthesized a ternary
PtRhSnO2/C electro catalyst, which produces electrical currents 100 times
higher than those produced with other catalysts. Scientists at the Kyushu
Institute of Technology, Japan have found that addition of TiO2, SnO2, and
SiO2 nanoparticles to the carbon-supported PtRu (PtRu/C) in the ratio 1:1
increased the short circuit current from 2.8 to 9.0 mA/cm2.
6.2 National Status
SPIC Science Foundationin Chennai demonstrated a 250 watts DMFC
in the early 2000s. Subsequently there has been no report from this group.
CSIR–CECRI has been addressing several issues related to DMFC. These
include Identifying and qualifying methanol tolerant catalysts and electro-
catalysts for enhanced methanol oxidation, PEMs with reduced methanol
permeability, customization of flow fields and end plates for stack building,
73
custom designing BOP with application centric approach and validation of
durability of components and system are focused.
The following are the list of electro catalyst supports that have been
found to yield better performance than the state-of-the-art catalyst reported in
the literature.
(i) Transition Metal Carbide supported Pt-Ru Anode catalyst (Methanol
oxidation).
(ii) Pt-Ru decorated self-assembled TiO2-Carbon hybrid nano structure
(EnhancedMethanol electro-oxidation).
(iii) Carbon-Supported Pt-Pd Alloy cathode catalyst (Methanol tolerant).
(iv) Carbon-supported Pt encapsulated Pd nanostructure as methanol-
tolerant oxygen reduction electro catalyst.
(v) Pt-Y(OH)3/C cathode catalyst.
These electro catalysts have not only been assessed for respective reaction
kinetics but also tested on single cell configuration (25 cm2) with standard flow
field using Nafion 117 as the electrolyte. Similar to the approach shown
above, different kinds of proton exchange membranes originating from Nafion
and also non-Nafion source particularly from natural and synthetic polymers
have been developed and validated with standard flow field and electro
catalyst configurations:
(i) Polyvinyl alcohol (PVA)-polystyrene sulfonic acid (PSSA) blend.
(ii) Mordenite-PVA-PSSA composite.
(iii) PVA-Sulfosuccinic acid (SSA)-heteropolyacid (HPA) mixed matrices.
(iv) Chitosan(CS)-Hydroxyethylcellulose (HEC)-phosphotungstic
acid(PTA) mixed matrices.
All these polymers have been configured specific to reducing
methanol permeability using different concepts of poly blending and cross
linking polymer chemistry with the possibility of realizing proton conductivity
close to Nafion 117. While doing so, the methanol impermeability has been
taken into consideration with a little sacrifice on proton conductivity. This gives
rise to a factor called “Electrochemical selectivity” that decides the choice of
appropriate polymer membrane suiting to the desired configuration of DMFC.
The following two tables show the different concepts used in evolving
the resultant macromolecular network and electrochemical selectivity obtained
for the competing polymer electrolyte membrane:

Besides electro active components, CECRI has also optimized flow
field pattern required for efficient DMFC operation and to avoid leakage. A 50
W self-sustained DMFC has been designed and evaluated for continuous
longer hours operation. It has been shown that by careful balancing methanol
and water, it is possible to customize the DMFC for an uninterrupted
operation. The present efforts are directed towards the following action plan:
Increase the gravimetric power density of DMFC stack to 200W/kg, improve
flow distribution, current distribution, metallic flow field design, MEMS based
bipolar plate, reduce methanol crossover, improved stack design,
lighter/thinner end and bipolar plates, miniature control system.
IIT Delhi developed 3 W stack based of direct alcohol (methanol and
ethanol) flowing alkaline electrolyte fuel cells and direct alcohol proton
exchange membrane fuel cell. They developed a direct ethanol fuel cell using
Nafion membrane and a novel bi/tri-metallic catalyst with a performance of 50-
70 mW/cm2. Work on non-noble metal catalysts for oxygen evolution and
reduction reactions is going on. They have developed direct glucose fuel cells
with power density of 5-10 mW/cm2. The mathematical modelling of SOFC,
PEMFC and DAFC is also carried out.
6.3 Gap Analysis & Strategy to Bridge the Gap
As mentioned earlier, DEFC has recently attracted much research
attention due to its non-toxicity, its availability from renewable sources and
low ethanol fuel-crossover compared with methanol. Ethanol is a hydrogen-
rich liquid and it has a higher energy density (8.0 kWh/kg) compared to
methanol (6.1 kWh/kg). But DEFC has low power output compared to DMFC.
On other hand DMFC has problem of fuel cross over which is less in DEFC.
The performance of the DEFC is currently about half that of the DMFC.
75
Reason being the electro-catalytic oxidation of ethanol in a direct ethanol
polymer electrolyte membrane fuel cell is known to be more complex and
incomplete than that of methanol. Low-temperature oxidation of ethanol to
hydrogen ions and carbon dioxide requires a more active catalyst with
excellent selectivity, which typically means a good combination of bimetallic,
trimetallic platinum based catalyst, is required than in conventional catalysts
used for DMFC. Thus investigation of ethanol electro-oxidation reaction
mechanisms on electrode is important and needs to be investigated. The
amount of catalyst used in direct alcohol fuel cell is normally very high and
efforts are required to address this issue. Methanol crossover is one of the
major obstacles to prevent DMFC from commercialization. There are very few
studies of short stack or stack development and associated engineering
issues. These need to be looked into.
Transfer of technology from abroad may be required for the
development of balance of plant for DMFC and DEFC. Packaging product
DEFC or DMFC as power source for portable equipment requires precise
design and optimization of design parameter for BOP and precise control of
the same. There are couple of Korean, Taiwan and German manufacturers,
who are in advance stage of commercialization for the use of DMFC and
back-up power for telecom tower, utility vehicle such as golf cart, scooter and
portable electronic equipment.
6.4 National Targets
Depending on the power capacity of the product, three main areas of
applications can be national targets such as:
(i) Consumer Electronics Applications: 50-250W with an energy density of
500-800Wh/L. Although India’s contribution to electronics industry in
general is only 0.7%, the Indian industry and R&D institutions in
general can provide breakthrough to portable fuel cell.
(ii) Other applications e.g.two wheelers, golf cart, mini trucks, residential
and small business establishments etc.: 1-5 kW having energy density
of 800 – 1000Wh/L.
(iii) Time schedule may be as follows:
(iv)
Fuel Cell Type Phase-I (2016-
2018)
Phase II (2019-
20)
Phase-III (2021-
2022)

DIFFERENT TYPES OF BIO-FUEL CELL
78
79
7.0 Different Types of Bio-Fuel Cell
7.1 Working Principle and classification of bio-fuel cell
The fuel cells, which use different forms of bio-catalysts, are normally
referred to as “Bio-fuel Cells”. They are relatively of more recent origin and
require significant extent of basic/ fundamental research before technology
development effort may be initiated in this country.
There are two major types of Biological fuel cells (or Bio-fuel cells): 1)
Microbial fuel cells employ living cells such as microorganisms as the catalyst
for the electrochemical reaction and 2) Enzymetic bio-fuel cells, which use
different enzymes to catalyze the redox reaction of the fuels.A generalized
schematic of a bio-fuel half-cell is presented in Fig. 4 and an overview of
different types of bio-fuel cells is presented in Fig. 7.
Fig.7: Schematic of a generalized half-bio-fuel cell. A fuel is oxidized (or
oxidant reduced) with the help of a biological component (organism or
enzyme), and electrons are transferred to (or from) a mediator, which
either diffuses to or is associated with the electrode and is oxidized (or
reduced) to its original state and thus act as a catalyst.
7.2 Microbial Fuel Cell
As mentioned above, a microbial fuel cell (MFC) converts chemical
energy of a fuel (generally a liquid) to electrical energy by the catalytic activity
of microorganisms, which helps to generate both electrons and protons at the
anode. Use of various types of microorganisms has been reported for this
purpose. For example, brevibacillus sp. PTH1 has been one of the most
extensively used microorganisms in a MFC system. Others include firmicutes,
acidobacteria, proteobacteria and yeast strains Saccharomyces cerevisiae
and hansenulaanomala etc.
80
Fig.8: Classification of bio-fuel cells.
Microbial bio-fuel cells have the major advantage of complete oxidation
of the fuels due to the use of microorganism as catalyst system and their
lifetime is generally quite long. Besides, as there is no intermediate process
involved, they are very efficient energy conversion devices. In addition, as a
fuel cell, a MFC doesnot need charging during operation. However, there are
certain bottlenecks. Power generation of a MFC is affected by many factors
including microbe type, fuel biomass type and concentration, ionicstrength,
pH, temperature, and reactor configuration.
The principle cell performance of MFCs lies in the electron transfer
from microbial cells tothe anode electrode. The direct electron transfer from
the micro-organism to electrodes is hindered by overpotential due to transfer
resistance. The overpotential lowers the potentialof a MFC and significantly
affects the cell efficiency. In this case, the practical outputpotential is less than
ideal because the electron transfer efficiency from the substrate to theanode
varies from microbe to microbe. Microorganism species do not readily
releaseelectrons and hence the redox mediators are needed. A desirable
mediator should have awhole range of properties: Firstly, its potential should
be different from the micro-organismpotential to facilitate electron transfer.
Secondly, it should have a high diffusion coefficientin the solution. Lastly, it is
Bio-fuelCell
81
suitable for repeatable redox cycles in order to remain active inthe electrolyte.
Widely used Dye mediators such as neutral red (NR), methylene blue
(MB),thionine (Th), meldola's blue (MelB) and 2-hydroxy-1,4-naphthoquinone
(HNQ) canfacilitate electron transfer for microorganism such as Proteus,
Entero-bacter, Bacillus,Pseudomonas and Escherichia coli. In the electron
transfer process, these mediators arereduced by interacting with electron
generated within the cell then these mediators inreduced form diffuse out of
the cell to the anode surface where they are electro-catalyticallyoxidized. The
oxidized mediator is then capable to repeat this redox cycle.Better performing
electrodes can improve the cell performance of a MFC because
differentanode materials can result in different activation of a polarization loss,
which is attributed toan activation energy that must be overcome by the
reactants. Carbon or graphite basedmaterials are widely used as electrodes
due to their large surface area, high conductivity, biocompatibility and
chemical stability. Also, platinum and gold are popular as electrode system
although they are expensive. Compared with carbon basedelectrode
materials, platinum and gold electrodes are superior in the performance of
thecells. Besides, they have a higher catalytic kinetics towards
oxygencompared to carbon based materials and hence the MFCs with Pt
based cathodes yieldedhigher power densities than those with carbon based
cathodes.Electrode modification is another way to improve MFC performance
of cells. An increase of 100-folds in current has been observed by using
(neutral red) NR-woven graphite and Mn4+-graphite anode instead of the
wovengraphite anode alone. Electrode modifications including adsorptionof
AQDS or 1,4-naphthoquinone (NQ) and incorporation with Mn2+, Ni2+,
Fe3O4 increasedthe cell performance of MFCs in their long-term operations.
In addition,the fluorinated polyanilines, poly (2-fluoroaniline) and poly (2, 3, 5,
6-tetrafluoroaniline)outperformed polyaniline were applied for electrode
modification (Niessen et al., 2006).These conductive polymers also serve as
mediators due to their structural similarities toconventional redox mediators.
A proton exchange membrane (PEM) such as “Nafion” can also
significantly affect a MFC system's internalresistance and concentration
polarization loss because the internal resistance of MFCdecreases with the
increase in the PEM surface area Compared with the performanceof MFC
using a PEM or a salt bridge, the power density using the salt bridge MFC
was 2.2 mW/m2 that was an order of magnitude lower than that attained using
Nafion.However, side effect is unavoidable with the use of PEM. For example,
the concentration ofcation species such as Na+, K+, NH4+, Ca2+, Mg2+ is
much higher than that of proton so thattransportation of cation species
dominates. In this case, Nafion used in the MFCs is not anefficient proton
specific membrane but actually a cation specific membrane. Subsequent
studies have implied that anion-exchange or bipolar membranes hasbetter
properties than cation exchange membranes.
82
Two promising applications of MFCs in the future are wastewater
treatment and electricitygeneration. Although some noticeabledevelopment
has been made in the MFC research, there are still a lot of challenges to
beovercome for large-scale applications. The primary challenge is how to
improve the cellperformance in terms of power density and energy efficiency.
In addition, catalytic effect ofbio-electrodes need to be further enhanced to
solve the problems caused by enzyme activityloss and other degradation
processes. Moreover, the lifetime of the MFC must besignificantly improved.
7.3 Enzymatic bio-fuel cells
In enzymatic bio-fuel cells (EBFCs) redox enzymes such as glucose
oxidase (GOx), laccase etc. are used as the catalysts that can facilitate the
electron transfer between substrates andelectrode surface. The electron
transfer mechanism may be of two types: i) Direct electron transfer (DET) and
ii) Mediator electron transfer (MET). In the former, the substrate is
enzymatically oxidized at the anode, producing protons and electrons which
directly transfer from enzyme molecules to anodesurface. At the cathode, the
oxygen reacts with electrons and protons, generating water.However, DET
between an enzyme and the electrode has only been reported with a
fewenzymes such as cytochrome c, laccase, hydrogenase, and several
peroxidases. Some enzymes have nonconductive protein shell so that
theelectron transfer is inefficient. To overcome this barrier, a mediator is
therefore used to enhance thetransportation ofelectrons. The selection and
mechanism of MET in EBFCs are quite similarto those of MFCs that are
discussed before.
There are still some challenges in usingMET in EBFCs, such as poor
diffusion of mediators and non-continuous supply. Therefore, modification of
bio-electrodes to realize DET based EBFCs has attracted most attention. Like
in any fuel cell, power density and lifetime are two important factors which
determine the cellperformance and the application of EBFCs. Significant
improvements have been made in recent times. These have been mostly
achieved by modification of electrode with betterperformance, improving
enzyme immobilization methods as well as optimizing the cellconfiguration.
The performance of electrodes for EBFCs mainly depends on: electron
transfer kinetics, mass transport, stability, and reproducibility. The electrode is
mostly made of gold, platinum or carbon as in case of conventional bio-fuel
cells. Besides these conventional materials, biocompatible conducting
polymers have also been used widely.
In order to maximize the cell performance, mesoporous materials have
been applied in many studies because of their high surface areasthus high
83
power density could be achieved. Moreover, many attempts using nano-
structuressuch as nano-particles, nano-fibers, and nano-composites as the
electrode materials. The large surface area by using these nano-
structuresleads to high enzyme loading and enables to improve the power
density of the cells.Recently, one of the most significant advances in EBFCs
is electrode modificationby employing carbon nano-tubes. Several research
activities have addressed the application of single wallcarbon nano-tube
hybrid system. The oriented assembly of short SWNT normal to
electrodesurfaces was accomplished by the covalent attachment of the CNT
to the electrode surface.It was reported that surface assembled GOx is in
good electric contact with electrode due tothe application of SWNT, which
acted as conductive nano-needles that electrically wire theenzyme active sites
to the transducer surface. Other studies have been reported on
improvingelectrochemical and electro-catalytic behavior and fast electron
transfer kinetics of CNTs.It was discussed that the application of SWNTs,
whichpossesses a high specific surface area, may effectively adsorb enzyme
molecules and retainsthe enzyme within the polymer matrix, whereas other
forms of enzyme-composites may suffer from enzyme loss when they were
placed in contact with aqueous solutions.Although recent advancement in
modification of electrodes appears to be promising due tothe improvement of
cell performance obtained, biocompatibility and nano-toxicity need to
befurther studied and addressed.
Successful immobilization of the enzymes on the electrode surface is
considered as anothercritical factor that affects cell performance. The
immobilization of enzyme can be achievedphysically or chemically. There are
two major types of physical methods, physicalabsorption and entrapment. The
first one is to absorb the enzymes onto conductive particlessuch as carbon
black or graphite powders. For example, hydrogenase and laccase
wereimmobilized by using physical absorption on carbon black particles to
construct compositeelectrodes and the EBFCs could continuously work for 30
days. Another physicalimmobilization method is based on polymeric matrices
entrapment, which usually showsmore stabilized enzyme immobilization. For
example, redox polymers could be utilized to fabricateenzymatic bio-fuel cells
system. For this, the electrodes were built by casting the enzyme-
polymermixed solution onto a 7 μm diameters, 2 cm length carbon fibers. It
showed that the glucose–oxygen bio-fuel cell was capable of generating a
power density up to 0.35mW/cm2 at 0.88V. Compared with the physical
immobilization which is unstableduring the operation, the chemical
immobilization methods with the efficient covalentbonding of enzymes and
mediators are more reliable.
However, there are still challenges for further development oflong term
stability of the enzymatic bio-electrodes and efficient electron transfer
betweenenzymes and electrode surfaces. Recent efforts have been given to
84
protein engineering, reliable immobilization method and novel cell
configuration.
7.4 Miniature enzymatic bio-fuel cells
The first micro-sized enzymatic bio fuel cell was reported in 2001.
Aglucose/O2 bio-fuel cell consisted of two 7 μm diameter, 2 cm long electro-
catalyst-coatedcarbon fibers operating at ambient temperature in an aqueous
solutionof pH 5. The areas of theanode and the cathode of the cell were about
60 times smaller than those of the smallestreported and 180 times smaller
than those of the previously reported smallest cell. The power density of the
cell was 64 μW/cm2 at 23 °C and 137 μW/cm2 at 37 °C, and the power output
was 280 nW at 23 °C and 600 nW at 37 °C. The results revealed that
theminiature enzymatic bio-fuel cells could generate sufficient power for small
powerconsumingCMOS circuit. Later, a miniature compartment-less
glucose/O2 bio-fuel cell operatingin a living plant was developed. Implantation
of the fibers in the grape leads to an operating bio-fuel cellproducing 2.4 μW
at 0.52 V, which is adequate for operation of low-voltage
CMOS/SIMOXintegrated circuits. The performance of the miniature enzymatic
bio-fuel cell was upgradedto 0.78 V operating at 37 °C in a ph 5 buffer. In
2004, a miniaturesingle-compartment glucose/O2 bio-fuel cell made with the
novel cathode operatedoptimally at 0.88 V, the highest operating voltage for a
compartmentless miniature fuel cell. The enzyme was formed by “wiring”
laccase to carbon through anelectron conducting redox hydro-gel, its redox
functions tethered through long and flexiblespacers to its cross-linked and
hydrated polymer, which led to the apparently increasedelectron diffusion
coefficient. The latest report on miniature glucose/O2 bio-fuel
cellsdemonstrated a new kind of carbon fiber microelectrodes modified with
single-wall carbon nano-tubes (CNTs). The power density of this assembled
miniaturecompartment-less glucose/O2 BFC reached 58l Wcm-1 at 0.40 V.
When the cell was operatedcontinuously with an external loading of 1 M
resistance, it lost 25% of its initial power in thefirst 24 h and the power output
dropped by 50% after a 48 h continuous work. Althoughfrom the practical
application point of view, the performance and the stability of the recently
developedminiature emzymatic bio-fuel cells remain to be improved, the
miniature feature and the compartmentlessproperty as well as the tissue-
implantable bio-capability of enzymatic bio-fuel cellessentially enable the
future studies on in vivo evaluation of the cell performance andstability in real
implantable systems.
In an effort to miniaturize the EBFCs, a versatile technique based on
CMEMSprocess for the miniaturization of electrodes has been developed. It is
centered aroundthefabricationof 3D microelectrodes for miniature enzymatic
bio-fuel cells. First, the functionalizationmethods for EBFCs enzyme
85
immobilization were studied. Then we apply finite elementapproach to
simulate the miniature EBFCs to attain the design rule such as electrode
aspectratio, configuration as well as orientation of the chip. Building an EBFC
based on this designrule is still underway.

research work has been carried out in many institutes around the world,
glimpses of which are presented here. The accelerated rate of publication
particularly during the last one decade is quite evident from Fig.6 presented

wastewater treatment and renewable energy generation. The Penn State

7.7 Applications of bio-fuel cells
Presently there are two practically applied systems; a test rig operating

as a biological oxygen demand (BOD) sensor, and also a biofuel cell has
been employed as the stomach of a mobile robotic platform ‘Gastronome’,
designed as the precursor to autonomous robots that can scavenge their fuel
from their surroundings (gastrobots). The original Gastronome ‘eats’ sugar

require manual feeding. Many applications have been suggested however,
and several of these are in varying stages of development.
The most obvious target for biofuel cells research is still for in vivo
applications where the fuel used could be withdrawn virtually without limit from
the flow of blood to provide a long-term or even permanent power supply for
such devices as pacemakers, glucose sensors for diabetics or small valves
for bladder control. The challenge of biocatalysis over a suitably long period is
particularly problematic in these areas, where surgical intervention could be
required to change over to a new cell and ethical constraints are
paramount.Ex vivo proposed applications are diverse. The large scale is
represented by proposed power recovery from waste streams with
simultaneous remediation by bio electrochemical means, or purely for power
generation in remote areas, the medium scale by power generating systems
for specialist applications such as the gastrobot above, and perhaps of
greatest potential the small scale power generation to replace battery packs
for consumer electronic goods such as laptop computers or mobile
telephones. The larger scale applications tend to be organism based and the
smaller scale ones more likely to be enzymatic. In the case of enzymatic fuel
cells, at least, the major barrier to any successful application is component
lifetime, particularly in view of the limited enzyme lifetime and problems of
electrode fouling/poisoning.
7.8 Conclusions
Extensive R&D activity is in progress throughout the globe including
India for laboratory level investigation on the various aspects of bio-fuel cell
with partial success. Prototypes have been developed only for a few
applications. Research into defining the reaction environment needs to be
conducted so that models of system behaviour can be created, validated and
employed. Necessary elements in this research include temperature variation,
pressure, fluid flow, mass transport (of nutrients, wastes and by-products) and
reactant conversion. Once these elements are considered it should become
possible to design a bio-fuel cell as a unit operation that can be employed as
a part of a larger process.
Significant development on both types of bio-fuel cells has been
achievedin the past decade. With the demands for reliable power supplies for
medical devices forimplantable applications, great effort has been made to
make the miniaturized bio-fuel cells.The past experiment results revealed that
the enzymatic miniature bio-fuel cells couldgenerate sufficient power for
slower and less power-consuming CMOS circuit. In addition, we have also
presented simulation results showing that the theoretical power
outputgenerated from C-MEMS enzymatic bio-fuel cells can satisfy the current
implantable medicaldevices.
89
However, there are several challenges for further advancements in
miniaturizedbio-fuel cells. The most significant issues include long term
stability and non-sufficientpower output. Successful commercial bio-fuel cell
development requires a ‘chemical engineering’ approach and requires the
joint effortsfrom different disciplines: biology to understand bio-molecules,
chemistry to gainknowledge on electron transfer mechanisms; material
science to develop novel materialswith high biocompatibility and chemical
engineering to design and establish the system. Considerable of fundamental
and interdisciplinary research is still needed in this country before a prototype
can be demonstrated in practice.
Proposed milestones for the development of this type of fuel cell may
be as follows:

8.1 Molten Carbonate Fuel Cell
8.1 International Activity
Recently, field tests of a 2 MW internal reforming system at the city of
Santa Clara, California and 250 kW external reforming by San Diego Gas and
Electric, California have been performed and a 280 kW system was started up
in Germany. It was followed by 1 MW system in Kawagoe, Japan. MCFC is
already in operation Germany and Spain which uses gases from waste water
treatment plants. South Korea is leading in the installation of MCFC units
using the FCE technology in recent times.
8.2 National Status
In India, CSIR-CECRI, Karaikudi had done work on molten carbonate
fuel cell (MCFC) in co-operation with TERI, New Delhi during 1992 to 1998
with support from Ministry of New and Renewable Energy, New Delhi. No
institution is currently engaged in the developmental activities of MCFC in the
country.
The R&D activities include synthesis of cathode materials by different
routes (combustion synthesis, solid state), preparation electrolyte matrix
structures by different routes, porous Ni electrodes (loose power sintering
(LPS), slurry casting (SC), tape casting (TC)). The largest size of electrolyte
they could prepare was ~1000 sq.cm. Current density achieved was in the
range 80 –100 mA/cm2 at cell voltage of 0.70 V/cell with 100 cm2 area
electrodes.
8.3 Recommendation
Even though very large (> 1MW) systems are commercially available
from the overseas manufacturers, the expertise currently available in India for
its indigenous development is negligible and therefore it is not recommended
to be a part of the mission mode programme. However, R&D programmes
may be taken up for laboratory scale demonstration to start with.
Proposed milestones for the development of this type of fuel cell may
be as follows:

ALKALINE FUEL CELL
96
97
9.0 Alkaline Fuel Cell
9.1 International Activity
Alkaline Fuel Cells (AFCs) were initially used in space applications by
NASA in the Apollo and Space Shuttle programs to provide electric power and
drinking water to the shuttle. In 1967, Dr Karl Kordesch of Union Carbide
developed and built an AFC motorbike.
Significant advantages of AFC technology led numerous companies,
both in North America and Europe such as Allis Chalmers, Union Carbide,
Varta, Elenco, Occidental Chemical and Siemens to get interested in
development of this technology for terrestrial applications. Industrial effort by
research and development work at many government and academic
institutions has made the possibility of applying AFC for household energy
requirements like inverter. In AFC, inexpensive carbon-and-plastic electrodes
are used, moreover inexpensive bipolar plate can also be used. AFC
electrodes are stable and not prone to the poisoning caused by carbon
monoxide, which poisons the platinum catalyst of the PEMFC. Nickel is the
most commonly used catalyst in AFC. The utilization of non-noble metal
catalysts and liquid electrolyte makes the AFC a potentially low cost
technology. The kinetics of the electrode reactions is superior in an AFC as
compared to acidic environment of other acidic Fuel Cells. AFC exhibits much
higher current densities and electrochemical efficiencies (up to 60%). it can be
operated at a wide range of temperatures (80 – 250oC). Presence of CO2
either in the fuel or the oxidant is not permitted for its operation. There is a
need to develop electro-catalyst, which does not corrode in potential window
of hydrogen oxidation potential. AFC has found typical applications in car,
boats and domestic heating.
9.2 National status
There is very little work on alkaline fuel cells in recent years although in
1980s’ CSIR- CECRI had a major program, which was discontinued. Recently
some work on catalysts for AFC has been reported from CSIR-CECRI and
IISc. Performance of AFC was studied and modelled at IIT-G using methanol,
ethanol and sodium borohydride as fuel.
9.3 Proposed National Plan
It needs to be established that AFC can operate with hydrogen and air.
Most of applications in space use hydrogen and oxygen, which is not practical
for terrestrial applications. With the advent of anion exchange membrane,
AFC with solid membrane could be advantageous. Developments of corrosion
98
resistant materials, non- noble metal catalysts etc. arestill the challenging
tasks.
Therefore development of this technology either in mission mode or
proto-type development mode is not recommended at this stage. However,
basic research work on efficient catalyst development and CO2 management
may continue.

DIRECT CARBON FUEL CELL
100
101
10.0 Direct Carbon Fuel Cell
10.1 Introduction
Direct Carbon Fuel Cell (DCFC) converts fuel such as granulated
carbon powder (10 to 1000 nm size) to electricity directly instead of burning it
to produce steam which can be used to produce electricity through a turbine
and generator. It is reported that the electrical efficiency of DCFC could be as
high as 70%. It is also reported that this process can reduce CO2 emissions
by 50% without sequestration. Molten salts such as lithium, sodium, Yttrium-
stabilized zirconium or potassium carbonate are used in these systems, which
operate between 600 to 850°C. The overall cell reaction is carbon and oxygen
forming carbon dioxide and electricity. Carbon derived from a large number of
agri-wastes can also be used in DCFC. DCFC operates at efficiencies more
than twice that of conventional combustion technologies and separate the
waste gases internally leading to a near pure CO2 exhaust stream that can be
easily captured for storage or commercial use leading to zero emission fossil
fuel or negative emission bio-fuel electrical power generation.
The overall cell reaction (C + O2 = CO2) is based on the complete
electrochemical oxidation of carbon to carbon dioxide (CO2) in a four-electron
process. It is reported that the thermodynamic efficiency slightly exceeds
100% - almost independent of conversion temperature, which is due to a
positive near-zero entropy change of the cell reaction (DS_ ¼ 2.9 J K_1
mol_1). Another advantage of a DCFC is that the fuel utilisation can reach
up to 100%, since a solid fuel is used. This is due to the fact that the reaction
product, CO2, exists in a separate gas phase and thus does not influence
activity of the solid carbon.
In the literature, several different concepts of DCFC based on different
electrolytes have been discussed. These are molten carbonate, molten
hydroxide or solid ceramic material YSZ (yttria-stabilised zirconia)
electrolytes, use of fluidized bed etc. EPRI has analysed the results from the
following institutions / companies in the USA:
Company Core Technology
Contained Energy (CE) MCFC
SARA Alkaline Molten salt
CellTech Power ( CELLTECH) Liquid metal anode with SOFC
Direct Carbon Technologies LLC (
DCT)
Fluidized bed with SOFC
SRI Circulating molten salt anode with
SOFC
Univ. of Hawaii Biomass Charcoal with aqueous

alkaline cell
Univ. of Akron SOFC with modified anodes
DCFC based on molten carbonate electrolyte (Lawrence Livermore
National Laboratory, USA) is the most investigated type. Power densities in
the range of 40 to 100 mW cm-2 (0.8 V cell voltage, 8000C) for different carbon
materials have been achieved. LLNL has demonstrated the use of
“turbostratic” carbon can overcome several challenges faced by earlier
groups, which used coal. The carbon particles and oxygen (ambient air) are
introduced as fuel and oxidizer, respectively. The slurry formed by mixing
carbon particles with molten carbonate constitutes the anode. At the anode
carbon and carbonate ions react to form carbon dioxide and electrons. At the
cathode, similar to other high-temperature fuel cells, oxygen, carbon dioxide
and electrons react to form carbonate ions. A porous ceramic separator holds
the melt in place and allows the carbonate ions to migrate between the two
compartments. Peak power densities of 120 to 180 mW cm-2 have been
reported using molten hydroxide electrolyte (Scientific Applications and
Research Associates, SARA).
The third concept is based on the combination of solid oxide fuel cell
(SOFC) and molten carbonate fuel cell (MCFC) technology. Peak power
densities of 10 to 110 mW cm -2 (0.7 V cell voltage) in a temperature range of
700 to 950°C using different carbon containing materials e.g. plastic (SRI
International) have been reported.
Direct Carbon Technologies, USA have demonstrated a DCFC which
combines SOFC and fluidized-bed technologies. Peak power densities up to
140 mW cm-2 (0.5 V cell voltage, 900°C) have been achieved using this
concept. CellTech Power LLC, USA formed in Jan 2006 is promoting DCFC,
which uses Liquid Tin SOFC concept. DCFC work has also been reported
from laboratories in PR China, KTH Sweden, ZEA Bayern, Germany TU
Munich, BNL, USA. Great progress has also been made at the Max Planck
Institute in Germany and the University of Queensland in Australia.
CSIRO’s (Australia) strategy has developed a fuel cell module that can
operate on low grade high carbon solid fuels at high efficiency. The cell
design, materials development program and fabrication technologies have
specifically focused on developing a device that can be easily up-scaled. This
has led to the use of conventional ceramic processing routes but novel cell
designs and materials to fabricate cells that can be easily stacked, connected
electrically and operated continuously on solid fuels for extended periods of
time with minimal degradation. This bottom up approach has led to the
development of a simple high performance cell design which can be operated
in a packed bed reactor without the need for fluidization. Furthermore the
103
system contains no molten components (which has been the strategy used by
many overseas groups). This should significantly increase the operating life of
the fuel cell system. A number of parallel developmental paths (e.g.
development of individual materials, fabrication techniques for scalable cell
design, fuel feed system and testing from small button cells to scalable tubular
cells) are being pursued to fast track technology development.
10.2 Technology Features
• Low operating cost - the ability to operate on low grade solid fuels will
lead to low overall operating costs.
• Flexibility - the modular design allows customization to a wide range of
power requirements.
• Low emissions – electrochemical oxidation in a membrane reactor means
that the waste products are separate and pure allowing them to be either
stored geologically or sold for commercial use within industry.
• Improved life time - novel mixed ionic electronic conducting electro-
catalysts eliminate the need for molten media within the fuel cell
increasing performance and system life time
• Scalable cell / stack design - unique packed bed design that allows for
simple robust low cost continuous feeding of fuel to the system. All cell
and system components have been designed for fabrication via
conventional low cost ceramics processing routs to allow for mass
production.
• Real world application - System performance evaluated on real world low
cost fossil, biomass and waste derived fuels.
10.3 R&D Requirements:
There are several technical gaps which require to be addressed. These
include better understanding of Anode Electrochemistry [ Mechanism for the
anodic reaction of coal, coke, Reactions and mechanisms of H, N,S (bound
and pyrite) under reducing conditions (E = -0.8 V vs Au/CO2,O2)] , effect of
impurities found in coal and coal-derived carbon: minerals, water , Transport
of CO2, CO32-, particulates and carbon in anode and matrix; gradients of oxide
and carbonate; role of water , Surface chemistry: functional groups, wetting
and site reactivity, Adaptation of cathode structures and catalysts for specific
needs of C/Air cell , Identify life-limiting processes such as corrosion. The
most important problems with hydroxide cells are (i) corrosion of materials
and (ii) degradation of the electrolyte due to formation of carbonates during
carbon electro-oxidation.
104
There is no R&D activity in this area presently in India. Taking into
consideration the large coal reserves in the Country,it may be worthwhile to
take up this activity in the country on a basic research mode

MICRO FUEL CELL

107
11.0 MICRO FUEL CELL
11.1 Introduction
The different kinds of fuel cells have been developed in micro form
also. These are known as Micro Fuel Cell (MFC). There is an ever increasing
demand for more powerful, compact and longer power modules for portable
electronic devices for leisure, communication and computing. Micro fuel cells
have the potential to replace batteries as they offer high power densities,
considerably longer operational & stand-by time, shorter recharging time,
simple balance of plant, and a passive operation. Micro fuel cells are ideal for
use in portable electronic devices such as:
• Prototype 50We self-air breathing micro fuel cell module.
• Laptop computers, Cellular phones, PDAs, 3G phones
• Portable electronic appliances, remote communication power packs
• Portable power packs for soldiers
• Emergency signs, variable message signs, emergency and back-up power
• Small transporters (wheel chairs, auto bikes, etc.)
11.2 Technology Features
In developing these technologies, CSIRO, Australia has given strong
consideration to mass production using micro-fabrication processes to deliver
low cost products for large volume markets. Low cost lithographic techniques
have been developed for fluid flow micro channels. Other features include:
Very passive device with no moving parts;
Self air-breathing or stack-powered air supply;
Operating power densities >100 mW/cm2;
100% fuel utilization, no air or hydrogen humidification, ambient
temperature operation;
Low catalyst loading;
Life time over 20,000 hrs achieved each for a two-cell stack and a 12 cell
stack (~10-20 W capacity) under constant and continuous cyclic load.
For comparison, batteries typically have life times of around 2,000-3,000
hrs;
Compared with Direct Methanol Fuel Cell (DMFC): low precious metal
catalyst loading, no toxic fuel, no fuel cross-over, no fuel recycling, no
CO2
5 generation/separation issues, high voltage per cell, high efficiency,
high power density;
Recharging time only few seconds as opposed to hours for batteries.

FUNDING PATTERN BY DIFFERENT
AGENCIES/ COUNTRIES

111
12.0 Funding Pattern by Different Agencies/ Countries
12.1 Global Scenario
In the advanced countries, R&D on Fuel Cell is being funded for more
than half a century initially to combat the rise in oil prices and later to combat
the global warming. Billions of dollars have been spent most of these
countries. It is difficult to get the exact figures from the earliest years.
However, some data are available for the more recent years. For example, in
2009, DOE, USA announced $41.9 million in Recovery Act funding to
accelerate fuel cell commercialization and deployment with industry
contributing another ~$54 million ( totalling ~$96 million) with the specific
objective of immediate deployment of up to 1,000 fuel cell systems in
emergency backup power, material handling, and combined heat and power
applications. Bulk of the money has been spent on PEMFC deployment. In
2010, International Partnership for Hydrogen Economy (IPHE) members
invested over $1 billion for hydrogen and fuel cell R&D and subsidies for the
technology deployment. Following table gives an idea of the level of funding
made by different participating countries during this year.

112
In March 2012, the Department of Energy (DoE), USA announced up
to $6 million available to collect and analyze valuable performance and
durability data for light-duty fuel cell electric vehicles, which use PEMFC
(FCEVs) and an additional up to $2 million available to collect and analyze
performance data for hydrogen fuelling stations and advanced re-fuelling
components. In an another announcement nearly $5 million have been
sanctioned under two projects both involving PEMFC, which aims at
lowering the cost of advanced fuel cell systems by developing and
engineering cost-effective, durable, and highly efficient fuel cell components.
In June 2013, DoE, USA announced additional budgetary provision of
up to $9 million in new funding to accelerate the development of hydrogen
and fuel cell technologies for use in vehicles, backup power systems, and
hydrogen re-fueling components. These investments were for strengthening
U.S. leadership in cost-effective hydrogen and fuel cell technologies and help
industry to bring these technologies into the market at lower cost
Similar trends have also been observed particularly for the
development of SOFC technology. In USA, DOE is the major funding agency
that caters SOFC research under the SECA program. In one financial year
(2013) they have invested $25 million to continue the Department’s research,
development, and demonstration of solid oxide fuel cell systems, which they
recognized to have the potential to increase the efficiency of clean coal power
generation systems, to create new opportunities for the efficient use of natural
gas, and to contribute significantly to the development of alternative-fuel
vehicles.
In Europe, the European Union had sanctioned a budget of 11 million
Euro in 2007 to a Consortium of nine research groups for the development of
materials, components and systems.
In China, The Ministry of Science and Technology (MOST) sets up the
development targets and funding levels for the various projects. During the
11th five-year plan (2006-2010), hydrogen and fuel cell technology research
was awarded RMB 182.5 million ($28.88 million) out of a total advanced
energy technology fund of RMB 634.3 million ($100.39 million). In addition, a
total funding of RMB 413 million ($65.37 million) was provided for energy-
saving and new energy vehicles, of which fuel cell vehicles were awarded
RMB 150 million ($23.74 million).
12.2 Indian Scenario
113
As expected, the level of research funding in India has been
abysmally low even though fuel cell research has been continuing in this
country for more than 25 years. India’s policy on fuel cells and financial
support is driven largely by four agencies, viz. Ministry of New and Renewable
Energy (MNRE), Department of Science and Technology (DST), Department
of Atomic Energy (DAE) and Council of Scientific and Industrial Research
(CSIR). Under its NMITLI program, CSIR has provided a total budgetary
support of about Rs.20 Crore during 2004-2013 for the development different
fuel cell technologies.
MNRE is a major supporter for hydrogen and fuel cell research in the
country for several decades. It has funded nearly Rs. 5.0 crores during 11th
Five Year Plan (2007-08 to 2011-12) and Rs.1.00 crores during 12th Five Year
Plan (2012-13 to December, 2014) for developing these technologies.
MNRE guidelines state that financial assistance for RD&D projects
including the technology validation and demonstration projects that involve
partnership with industry/civil society organizations should normally be
restricted to 50% of the project cost. However, for any proposal from
academic institutions, Government/non-profit research organizations and
NGOs, Ministry may provide up to 100% funding. Private academic
institutions should adhere to certain conditions for availing project grants from
the Ministry.
DST has been supporting several basic R&D program in various
hydrogen technologies in the country through SERC (presently SERB).
Several projects on PEMFC have been covered under this scheme. The
project budget details are not easily accessible. Besides this route, DST
through TIFAC has supported few hydrogen research programs. On a mission
mode through the IRHPA programs DST has sanctioned a project to ARCI to
set-up a fuel cell technology Centre with a specific aim of developing and
demonstrating PEMFC in decentralized and transportations applications. The
total outlay for the 10 year project is about ~Rs.24.00 crore for the period
2004-2014 ( the project includes man power costs of all scientists ,
infrastructure cost such as rent and maintenance, Utilities costs such as
electricity, water etc., besides the development costs). Future plans are not
clear at the moment. DST has also funded several faculty/ students exchange
programs under International collaboration some of which have been used for
work on PEMFC. DST has also signed an agreement with UKRC in 2011for
supporting projects specifically on fuel cells and one of the projects is on
PEMFC with an outlay of Rs.3.49 crore.
DSIR has sanctioned a project on commercialization PEMFC in 2011-
12 with a project cost of Rs. 9.5762 crores with DSIR contribution being
114
Rs.3.269 crores under their Technology Development and Demonstration
Program (TDDP).
BHEL, in addition to the present project on development of High
Temperature PEMFC, proposes to set up a Centre of excellence on Fuel
Cells at BHEL Corporate R&D, Hyderabad at a tentative project outlay of
Rupees 12-15 Crores to carry out several LT-PEMFC and HTPEMFC
projects.
Tata Motors for their fuel cell bus program is reported to have invested
substantial sum of money.
Mahindra and Mahindra who have invested in several hydrogen,
hydrogen + methane vehicle projects are also reported to have earmarked
some funds for PEMFC development for transportation applications.
The major oil and gas industries are reported to have formed a
consortium, which is also supporting some projects on PEMFC.
DRDO has made substantial investment for their fuel cell programme
since 1990, which has given them a significant dividend as follows:
NMRL has developed complete knowhow of PAFC based power plants
ranging from a few kW to > 10 kW. The development was done through
successive projects and the funds outlay for the same is mentioned below:
i) 1990-2000: Material development and low power stacks along
with methanol reformer technology development : ~ Rs 1.0 Crore
ii) 2000-2010: Development of assorted power systems ranging from
1 – 15 kW based on PAFC complete with all accessories and
development of capsule power plants for underwater applications
~ Rs 10.0Crore.
iii) 2010- 2015: Development of underwater power generation
prototypes for several 100 kWs along with other advanced
systems for defence applications ~ Rs 30.0Crore.
iv) 2015-2025: Plans to induct systems to underwater platforms and
man-portable generators along with onsite silent generators for
defence and civilian applications ~ Rs 100 Crore.
In addition DAE and ISRO have also allocated funds for several
internal programs on fuel cells; the exact figures are unavailable at this stage.
Besides, agencies like University Grants Commission (UGC) and All
India Council for Technical Education (AICTE), CSIR, DRDO, ISRO
115
(RESPOND) and BRNS have also provided smaller grants primarily to
academic institutions.

14.0 CONCLUSIONS AND RECOMMENDATIONS
14.1 With the growing population and its increasing standard of living, the
demand for energy is becoming higher continuously. In the long run this demand
for energy can’t be met by the depleting fossil fuels throughout the world,
including India. It is therefore, pertinent to develop clean and green alternate
energy sources, which may protect the environment by not creating any more
pollution / with reduced level of pollution in the production of electricity and
running the vehicles. One of such alternate energy technology is fuel cell
technology and therefore, efforts are being made world over to develop them in a
commercially viable manner. It is an energy conversion device that converts
chemical energy of a gaseous / liquid (in some cases solid) fuel into electrical
energy by electro-chemical reaction. Efforts are being made to make this
technology commercially viable by enhancing energy conversion efficiency,
electrode – electrolyte interface reaction, reducing the cost of the catalyst etc.
14.2 Various kinds of fuel cells have been developed over the past few
decades. They are classified primarily by the kind of electrolyte they employ. This
classification determines the kind of electro-chemical reactions that take place in
the cell, the kind of catalysts required, the temperature range in which the cell
operates, the fuel required, and other factors. Important types of fuel cell under
development are: Low and high temperature Proton Exchange Membrane Fuel
Cells (LT- & HT-PEMFC), Direct Methanol Fuel Cells (DMFC), Phosphoric Acid
Fuel Cells (PAFC), Alkaline Fuel Cells (AFC), Molten Carbonate Fuel Cells
(MCFC), Solid Oxide Fuel Cells (SOFC). In addition, there are a few types of
more recent origin, which have also gained significant importance in recent
years. These are MEMS based micro-fuel cells (MFC) for powering the micro-
electronic devices, bio-fuel cells (BFC), which uses micro-organisms as the
catalyst for the redox reaction and solid carbon fuel cell (DCFC) in which solid
carbon can be used as the fuel. In addition to the fuel cell stack composed of
several single cells (number depends on the desired power to be delivered) a
fuel cell power source consists of fuel tank (with or without reformer), source of
oxidant (air or oxygen), power conditioner (DC/AC convertor) waste heat
exchanger, exhaust system etc.
14.3 The fuel cell technology development is presently at an advanced stage in
the developed countries like USA, Canada, Germany, France, United Kingdom,
Australia, Japan, etc. At present it is very costly and well-guarded technology
through patents due to its extremely high marketpotential. Transfer of technology
may require heavy financing and Indian industries may not be in a position to
123
afford the same. So there is a growing need and compulsion to develop the
technologies within the country and deploy them for different applications for
large scale trial and performance evaluation.
14.4 The Government of India (GOI) has been supporting development of
technologies in the area of hydrogen energy and fuel cells for quite some time,
which has created a good expertise and infrastructure base. A well-framed
national program with participation from various academic institutions, R&D
establishments and industries with expertise in different areas need to be
launched in the country to develop this technology, manufacture in large
numbers and demonstrate their application potentiality for the benefit of the
society at large. Application areas of the developed products, it be mobile towers
or transportation or any other kind of applicationshould be chosen carefully so
that the requirements of the user are fully satisfied. In addition, areas are to be
identified for long term / futuristic R&D, which also require adequate financial
support.
14.5 Several government laboratories and academic institutions together with a
few private organizations are actively pursuing different kinds of R&D
programmes in this country for the last couple of decades. Considerable
expertise and infrastructure at different locations have already been developed.
In certain cases know-how’s have been transferred to industry and limited scale
production for particular type of fuel cell (PAFC) has also been initiated
particularly for defence use. Regular production even for the purpose of large
scale demonstration for other types of fuel cells is still a long way to travel.
DRDO, CSIR, MNRE and DST have been the major funding agencies for these
activities. Industry participation for the developmental projects, which is an
important pre-requisite for technology development and demonstration, is still at
its infancy.
14.6 The most successful Research and Developmental effort in the area of fuel
cell technology in this country has been registered by DRDO particularly for
PAFC. They have transferred the developed technology to an Indian Industry,
who has manufactured 24 Nos. of 3kW stack and delivered them back to DRDO
under a buy back arrangement. The industry is ready with the manufacturing
facility, which can be utilized for additional units in case a civilian utility is
identified and necessary funding is made available to them.
14.7 PEMFC is of two types – low and high temperature PEMFC. The LT-
PEMFC operates at less than 800C, whereas HT-PEMFC operates in the
124
temperature range of 120-1800C. The LT-PEMFC can tolerate CO level in the
hydrogen fuel up to a level of 10-20 ppm whereas HT-PEMFC can tolerate more
than this limit (up to 30,000ppm). LT-PEMFC requires humidification of
membrane, whereas it is not required for HT-PEMFC. The catalyst and
membrane materials for LT-PEMFC are still imported, whereas catalyst and
membrane materials for HT-PEMFC are at under advanced stage of
development in the country. The bipolar plates for both PEMFC have been
developed in the country. Due to rapid start-up and shut down, thermal cycling
and load following capability of PEMFC, there is enormous application
potentiality like for stationary & distributed power generation and transportation.
It is not as cheap as PAFC. It is costing around Rs.10 lakhs per 3 kW unit. The
cost cannot come down until there are many players e.g. bipolar plates are made
at present by machining but these can be moulded directly, it would become
cheaper. If any component is monopolized, its cost cannot come down. Many
groups are engaged in the development of membrane, but success has been
achieved in making PBI membrane for HT-PEMFC. Alternate to nafion
membrane is yet to be found out. CSIR has made 1 kW LT-PEMFC and got
tested through a third party in Chennai for 500 hours operation.
14.8 In the country LT-PEMFC has been developed upto 20 kW capacity by
different organizations. Thus, the country is in advanced stage of development of
LT-PEMFC and has adequate experience in the fabrication of fuel cells and its
stack building along with testing and validation protocols. The same experience
may be useful in rapid development of HT-PEMFC. A number of institutions and
industries are also engaged in the development of materials, components,
modules and systems of HT-PEMFC. The development targets for LT-PEMFC
can be shorter duration than that for HT-PEMFC. The time target for the
development of HT-PEMFC can also be made of shorter by providing more
funding. The specific targets for capacity can be set for the development of
PEMFC (LT-PEMFC and HT-PEMFC) systems like for stationary power
generation applications 1-5 kW, small trucks 3-10 kW, medium trucks 10-15 kW,
large trucks and submarine application 25 -50 kW and buses 50-100 kW.
14.9 It is proposed that the Development and Demonstration of minimum 5
units each of stand-alone LT-PEMFC and HT-PEMFC systems of capacities 1, 3
& 5 kW with a minimum of 50% indigenized components with electrical efficiency
37-40%, minimum 1000 h operational life and less than 10 mV / 1000 h
degradation to be operated with bottled hydrogen and air may be taken up
immediately. Sites for demonstration may be chosen suitably are to be identified
125
by the project proposers. For the development of PEM fuel cell technology,
different plausible issues to be taken up are:
(i) Membrane preparation with longer durability / stability, reduction of
platinum loading or use of non-noble metal as catalyst to lower the
cost
(ii) Membrane electrode assembly (MEA) for generating maximum power
density with the given weight
(iii) Fabrication of complete stack with complete characterization
(iv) Integration of stack with balance of system, sealing of stack, analysis
and final testing etc.
14.10 During the development of PEM fuel cell the manufacturing techniques
should be mastered for the following components / sub-systems / systems:
(i) Mass production of catalysts, carbon paper/wire mesh and bipolar
plates (casted)
(ii) Automation for uniform coating of catalyst on electrodes
(iii) Automatic assembling of Membrane electrode assemblies (till now
manually made) and high speed sealing of cell components.
(iv) Automated of high speed assembly of stacks
(v) Assembling system controllers & invertors
(vi) Integration of balance of system development (air moving devices,
thermal management devices, motors, pumps)
(vii) Integration of sub-systems into complete fuel cell system
14.11 For the development and demonstration of PEM fuel cell, the following
are suggested:
(i) The work and the infrastructure created under the above mentioned
research, development and demonstration (RD&D) activities will form a
part of long term technological development programme on PEM Fuel
Cell.
(ii) Importing of stacks may be allowed only for indigenously developing
balance of systems or accelerating development of Ancillary and not
for demonstration. Import of Membrane/MEAs may also be considered,
if it becomes absolutely necessary for the interest of the project. In
such a case, it must be ensured that the assembled stacks would meet
the specifications / performance / operation conditions of the imported
stacks.
126
(iii) The focus will be on the development of most critical to least critical
components and finding their solutions.
(iv) One of the organizations involved in the project, preferably an R&D
institution with public funding would be identified as the nodal
organization responsible for the ultimate delivery.
(v) Activities of all the sub-projects would be guided and monitored
regularly by the concerned nodal organization as per the requirement
to meet ultimate objective of the Project.
(vi) There will be appropriate exit provision particularly for the sub-projects
in case the progress does not appear to be satisfactory for what may
be reason.
14.12 The capital cost of PEMFC stack is high, which needs to be subsidized.
Most of the methods developed in Indian laboratories for PEMFC components
are only in laboratory scale / in the scale of semi-automated processes. There is
urgent need to develop the manufacturing methods quickly.
14.13 R&D activity on HT-PEMFC has started late in this country. However,
CSIR-NCL has made significant contribution through synthesis of indigenous PBI
membrane material, which may go a long way to maintain an advantageous
position in the international arena. Considering the enormous advantages of this
type of fuel cell particularly in terms of impurity tolerance of the fuel, better water
management and possibility of combined heat and power output, it is proposed
that this country takes up the development of this variety of PEMFC on highest
priority.
14.14 Solid Oxide Fuel Cell (SOFC) has the capability of using different fuels i.e.
besides hydrogen; it can use other fuels like gasoline, alcohol, natural gas, bio-
gas etc. It operates at 700-8000C. The most attractive feature of SOFC is high
power density. Thermal cycle ability is quite poor and high cost is a major issue.
Globally it has been demonstrated in the capacity range of 10 to 100 kW systems
and in India a 500 W unit (stack of 20 cells) with a current density of 500 mA/cm2
was demonstrated. Planar type technology is preferred over tubular type SOFC
due to higher current density, but its fabrication & balance of system in tubular
type is much easier. In planar SOFC, reliability depends on the high temperature
glass sealant, which has not been successfully developed in the country. Once
the technology is developed, vendors may be identified for production and scale-
up of system capacity for demonstration. Subsequently mass production may be
taken up in Public-Private-Partnership mode. For the development of this
127
technology in the country, it is proposed to undertake the following activities on a
mission mode approach:
(i) Development of components, stacks and balance of system for
planar / tubular (anode / cathode / electrolyte supported) and their
demonstration in the laboratory.
(ii) Preparedness for mass production of developed components /
modules / systems - Involvement / Development of vendors /
manufacturers.
(iii) Manufacturing of components / modules / systems for field
demonstration.
(iv) Development of standards for the developed modules / systems and
their commercial deployment.
(v) Creation of test facility / recognition of existing facilities.
(vi) Deployment of these modules / systems for different applications like
power supply units in remote areas and back-up power units in urban
/ rural areas etc.
(vii) Cost reduction by mass scale manufacturing and deployment of
systems.
(viii) Improvement in the system for increasing of durability of the system.
(ix) Development of standalone systems up to 100 kW capacities
different phases with partly imported components may be taken up
on a mission mode.
14.15 Although there have been research and development activities in the
country in the area of DMFC and DEFC, commercialization of this technology is
far away. A number of improvements are to be done before this technology can
be used on a large scale. Development and demonstration of direct alcohol fuel
cell systems may be taken up for niche applications like micro-processor
controlled devices. The R & D activities may be continued in these areas. The
transfer of technology from abroad balance of plant for DMFC and DEFC may be
explored to integrate with the indigenously developed stack. There is need to
develop compact systems, which can be fitted into the space available in the
devices. It could be developed and demonstrated in small capacities (up to
250W) to start with but later it may be enhanced a 5kW stack with power
densities of the order of100W/kg.
14.16 AFC technology has been demonstrated with a life of 20,000h of operation
with pure hydrogen and oxygen. Use of air instead of oxygen increases the cost
of operation due to addition of scrubbers. When air is passed on to the cathode,
128
KOH reacts with CO2 and forms K2CO3. CO2 is recovered in scrubbers. It uses
Nickel catalyst, whereas Pt is used in PEM fuel cells. Therefore its cost is
expected to be low. AFC was developed at laboratory scale in the country, but
could not be scaled up successfully. This technology may be developed
indigenously by indigenization of commercially available technology from abroad
in case some specific areas of application is identified. The AFCs of capacity in
the range of 1-3 kW have good market. Various countries have commercialized
AFC of capacities from 100 W to 3 kW as power packs with the established
technology. AFC can be operated at the highest efficiency i.e. upto 60% in the
temperature range from 70 to 120oC. It can also be operated in the higher
temperature range i.e.100–1200C. Nickel catalyst, although cheaper than
Platinum, gets corroded with a consequent deterioration of power density.
Thussignificant amount of basic research is still necessary in the country before a
serious technology developmental effort is initiated.
14.17 MCFC operates at a higher temperature and requires no external
reformer. The fuel is reformed internally to hydrogen. Very large capacity
(>1MW) units are in operation in some of the advanced countries. In India work
on MCFC was carried out during 1992 to 1998, by a couple of organizations only
with financial support from MNRE. However, currently there is hardly any
expertise to develop the basic fuel cell stack. Considering several advantages of
this type of fuel cell particularly as a distributed power plant, it is recommended
that the country may take a renewed interest in the R&D mode to develop the
technology in near future.
14.18 Microbial fuel cells (MFCs) use biocatalysts, which offer significant cost
advantages over traditional precious-metal catalysts through economies of scale.
The magnitude of power reported by MFC is several orders less than the
conventional chemical fuel cells. The applications of MFCs are portable
electronics, biomedical instruments, military and space research etc. The major
application area emerged since recent past for MFC is sewage treatment and
generation of power. Keeping in view of the above, it is recommended that
research and development work may be supported for specific applications.
There is an ever increasing demand for more powerful, compact and larger
power modules for portable electronic devices for leisure, communication and
computing, which may be supplied by the MFC. The MFCs can also be deployed
in large transport vehicles such as cars and trucks. CSIRO, Australia has given
strong emphasis to mass produce and deliver low cost products for large volume
markets. The life time is expected to be more than 20,000 hours. Keeping in view
129
of the above, it is recommended that research and development work may be
supported.
14.19 The Direct Carbon Fuel Cell (DCFC) is the next generation fuel cells at a
high operating temperature. These systems may be developed to operate on low
grade abundant fuels derived from coal, municipal and refinery waste products or
bio-mass, which will lead to a near pure CO2 exhaust stream that can be easily
captured for storage or commercial use leading to zero emission fossil fuel or
effectively a negative emission. CSIRO, Australia is one of the pioneering R&D
organizations in this area. Their strategy has been to develop such fuel cells that
can operate on low grade high carbon solid fuels at high efficiency. A number of
parallel developmental paths (e.g. development of individual materials,
fabrication techniques for scalable cell design, fuel processing and feed system
together with testing from small button cells to scalable tubular/planar cells are
being pursued on a fast track technology development. Having a very large
deposit low grade coal India can also take the advantage by developing this
unique technology. The technology has certain relationship to SOFC and MCFC
technologies. It is therefore recommended that DCFC may be developed in
conjunction with SOFC technology, which is poised to be taken up in a mission
mode.
14.20 The country has the potential to catch up with what is going on
elsewhere. However, it requires identification of the important issues and the
barriers, which are coming in the way of the development and commercialization
of the technologies. A few of them are listed below:
i) Inadequate funding: The most important limitation of the country’s Fuel
Cell development programme is the meager funding pattern together with
the lack of industrial participation and user pull. This is evident from the fact
that a consistent and enhanced funding together with identification of
specific demand by the defence forces has generated the best possible
dividend for DRDO. They have earned the credit of having the very first
indigenous fuel cell technology pressed into service. Such a concerted effort
is missing in case of other programmes of the country. Most of the methods
developed in Indian laboratories for PEMFC components are only in
laboratory scale and at best by semi-automated processes. There is urgent
need to develop manufacturing methods and large scale deployment
requiring adequate funding.
130
ii) Nature of the funded projects: The methods followed for sanctioning of
the projects by various funding agencies need to be critically analyzed. Most
of them are short term projects of academic interest. There is hardly any
follow-up or continuity of the projects aiming at technology development.
Multi-disciplinary groups do not collaborate to deliver a technology or
device. Projects normally are not formulated with sufficient micro-detailing
and the review mechanisms are also inadequate for a meaningful delivery.
iii) Invitation to submit projects (expression of interest): Instead of the
current system of uninvited proposals, the funding agencies either
individually or collectively may call proposals on specific aspects of
technology development rather than on general themes. The milestones
and time frames are required to be much better articulated and every effort
may be made to adhere to the same throughout the duration of the projects.
iv) Nature of human resource employed under the projects: Another major
issue is the nature of human resource employed in the projects. Hitherto,
the human recourse for the projects is in the form of research scholars and
technical assistants following DST/ CSIR guidelines. For technology
development projects this model will not work. Research papers need not
be the only form of output for these projects and therefore research fellows
may not be the only type of human resources employed in these projects.
People with hard core engineering skill will be preferred for the projects
aiming at technology development
v) Grant-in-aid to the participating industries: Participation of industries
particularly for the “mission mode” projects needs to be made compulsory.
Depending on the nature of their activities and the corresponding
investments required to be made by the industry vis-à-vis expected return,
grants-in-aid may be sanctioned to the industry varying between 30 and
70% of the project cost. Only soft loan may not be sufficient to ensure
participation of the industries.
vi) Collaborative projects with foreign institutions: Collaborative projects
with foreign institutions have mostly been limited to academic exchanges.
While it may be important to encourage such exchange, true technology
development does not take place through this route. A mechanism needs to
be developed for research institutions involved in applied research to sign
exclusive agreement, wherein the IP rights are shared according to the
contribution and a joint developmental work is carried out. Sometimes, this
131
may involve funding to the foreign partners for their inclusion in such
projects.
The Department of Science &Technology, sometime back signed an
exclusive agreement with UKRC, United Kingdom to promote R&D in the
area of fuel cell with a committed investment of £ 6 million. One of the
projects sanctioned under this scheme was on PEMFC and the other two
were on SOFC. Formulation of more such projects may be attempted.
vii) Transfer of technology from abroad: The technology of fuel cells all
across the globe is closely guarded and well-fortified by patents regime due
to its extremely high potential market. Another major challenge in making
fuel cell a viable technology in India is to obtain the know-how of the fuel cell
technology. Transfer of technology may require heavy financing and Indian
industries may not afford to finance unless the policy measures support
such a move.
viii) Setting-up of Testing Centers for Fuel Cells in the country: As a part
oftechnology development programme, the country must have at least one
centralized “Fuel Cell Testing Center” for different types of fuel cells, if not
more than one center specific to different fuel cells at different locations, for
third party evaluation of the units to be developed by the different research
groups. Sufficient manpower and budget need to be allocated for such
centers. An ARAI kind of set-up will be preferred.
ix) Availability of Hydrogen: Another major issue is setting up of a viable
hydrogen supply chain. Along with fuel cell development, the funding
agencies should also support short and long term projects on hydrogen
generation and storage. Projects such as photo-electro-chemical method to
produce hydrogen are really long term and the fuel cell development/
deployment cannot wait for such development.
x) Estimate of Hydrogen Requirement: Based on the milestones presented
in the Chapter on ‘Action Plan, Financial Projection and Time Schedule of
Activities’ and assuming that there will be at least two units of each of the
capacities mentioned therein one needs to test at least 1500 kW of fuel cells
of different capacities for a period of at least 1000 hours each. This means
that there will be a generation of 1.5 million kWH and corresponding amount
of hydrogen is required to made available for this developmental activity.
Assuming further that the units will be operated on an average of 50%
132
energy efficiency with fuel utilization of 75%, around 1000 liter (at STP) is
required for generation of 1 kWH of energy. Thus the total amount of
hydrogen requirement for the entire programme will be around 1500 million
liters of Hydrogen at STP during the next seven years. This is equivalent
to around 85,000 cylinders of hydrogen (50 liter water capacity and at 350
bar pressure). A parallel developmental activity is required for timely supply
of this huge amount of hydrogen.
xi) Setting up of a H2FC Centre: In order to coordinate and manage the
overall developmental programme and to bring all the projects to their
logical conclusion, it may be essential to set-up an “autonomous center”
under the ministry with full administrative and financial autonomy. In case, it
is difficult to set up a physically distinct centre at a specific location, one can
conceive of a “virtual centre” having its controlling unit under the ministry
different nodes spread across the country particularly at locations (existing
Institutes) where major programmes will be pursued.
xii) Policy Measures: The programmes supported by different funding
agencies in India are not correlated/ coordinated. It has been noticed that
some investigators approach different funding agencies with small changes
in the objectives and get support from more than one source. It seems that
there is no check for such projects and in many cases there is no continuity
in work. Even if all the objectives of the projects cannot be met, an analysis
of these results would be useful in sanctioning future projects. This applies
to all funding agencies. It requires having a common platform to identify and
support RD&D programs.
Policies are required to be in place to overcome the present issues
related to issuance of clearance for carrying out large scale field
trials, optimized manufacturing of specific materials and
components on a repetitive basis.
Incentives for Indian industries, who engage in manufacturing.
Additional incentives for industries that use at least some
components manufactured indigenously.
Incentives to users for using such systems may be extended similar
to what is offered to the users of other renewable energy
technologies such as solar and wind.
Human resource should be strengthened to retain the knowledge
base developed so far.
133
Specific Recommendations
14.21 Categorization of the Projects
Based on the level of maturity of the expertise and the importance of the
type of Fuel Cells, there may be three different categories of projects, which may
be funded to the different extents. These are:
i) Category I: “Mission Mode Projects (MMP)” having the ultimate
objective of limited scale manufacturing of different capacities standalone
systems, which may be demonstrated under field condition for the purpose
of performance evaluation. Industry participation is compulsory for this
category. Fuel Cell systems proposed to be developed under this category
are:
a) HT-PEMFC (Some IPRs on the fuel cell components have already
been developed in the country)
b) LT- PEMFC (Membrane material is still being imported in the country;
but stacks up to 25kW capacity have been fabricated and tested in the
country)
c) Planar SOFC (Success has been obtained in lower capacity (up to 1
kW range in the country)
d) PAFC (Taken-up on large scale manufacturing (up to 3 kW) for
application in the strategic sector. It is yet to be taken-up for the
civilian sector)
Detailed milestone of this activity is presented in Chapter on ‘Action Plan,
Financial Projection and Time Schedule of Activities’.
It is proposed to form consortiums consisting of R&D laboratories,
academic institutions and industries for each of the systems; one of them
preferably a R&D laboratory may be identified as the lead organization.
Following are the lead institutes identified for the purpose:
a) HT-PEMFC with combined cycle: Joint Lead Institutes - CSIR-NCL,
Pune and CSIR-CECRI, Karaikudi)
b) LT- PEMFC: Lead Institutes - CFCT, Chennai and/or CSIR-CECRI,
Karaikudi/ BHEL R&D, Hyderabad.
c) Planar SOFC: Lead Institute - CSIR-CGCRI, Kolkata
134
d) PAFC:Lead Institute NMRL, DRDO, Ambernath and/or BHEL R&D,
Hyderabad
ii) Category II: “Research & Development Projects (R&DP)” having the
objective of laboratory demonstration of critical systems and sub-systems
preferably with innovative approaches. Industry collaboration is preferred
but not essential for this category. Following are the fuel cell systems to be
considered under this category:
a) DMFC/DEFC
b) MCFC
c) BFC
iii) Category III: “Basic/ Fundamental Research Projects (B/FRP)” aiming
at carrying out basic/ fundamental research (including modeling) on
different aspects of any fuel cell system except the ones mentioned
above.
14.1 Budgetary Provision
It is recommended that an overall budgetary provision of Rs.750 Crore is
allocated for the complete fuel cell development programme over a period of next
7 years (up to the financial year 2022-23); 80% of this may be earmarked for
category I projects, 10% each for the other two categories. Complete milestone
of the programme together with the approximate financial outlay (sector wise) is
given in the Chapter on ‘Action Plan, Financial Projection and Time Schedule of
Activities’
14.23 Supply chain for Hydrogen
A parallel developmental activity is to be initiated for supply of around
1,500 million liter of high purity hydrogen for testing of the different capacities and
different types of fuel cells proposed to be developed under this programme.
14.24 Expression of Interest
Particularly for the “Mission Mode Projects” the ministry should invite
expression of interest from the interested research groups and industry followed
by formation of the consortium and identification of lead organization.
14.25 Virtual Fuel Cell Institute
135
For the purpose of efficient formulation and project management including
rigorous monitoring a Virtual Fuel Cell Institute may be created under the aegis of
the Ministry of New and Renewable Energy to bring all the concerned
stakeholders such as Ministries, Departments, academicians, researchers and
industry under one umbrella to work together in a systematic and focused
manner. This Institute may undertake following activities:
(i) Development of a mechanism to pool the resources of different Ministries,
Departments, International Funding Agencies and other agencies.
(ii) Identification of expertise available with various institutions / industries and
develop Mission Mode Projects utilizing the available expertise with the
aim to develop components, sub-systems and integrate them, which can
be mass produced and deployed in the country.
(iii) Monitoring the progress of the work done under the projects to achieve the
targeted goals in the time bound manner.
(iv) Co-ordination among the institutions for demonstration of developed
systems in field and comparison of various fuel cell technologies.
(v) Development of a mechanism / modality to incentivize the individuals and
the institutions involved in the development of a product.
(vi) Conducting market survey for business potential of fuel cell in India
(vii) Testing & benchmarking the components / prototypes / systems of fuel
cell.
(viii) Development of safety guidelines and standardization of on-board cost
effective storage / transportation
The Institute should have a Directorate with required administrative and
financial autonomy. All the members of the project team working at different
locations (including the PIs) would be collectively responsible to this directorate,
so far as the project activities are concerned.
